Start Screen Mirroring in Control Center with AppleScript - applescript

Question

I want to start Screen Mirroring from my MacBook to my AppleTV with a keyboard shortcut. I used Automator's Recording function ("Watch Me Do") to record the three necessary clicks (open Control Center, click on Screen Mirroring, click on Apple TV). This is the resulting code:
-- Click the “Control Centre” menu bar item.
delay 0.608482
set timeoutSeconds to 2.0
set uiScript to "click menu bar item 2 of menu bar 1 of application process \"Control Centre\""
my doWithTimeout(uiScript, timeoutSeconds)
-- Click the “<fill in title>” button.
delay 0.84342
set timeoutSeconds to 2.0
set uiScript to "click UI Element 6 of group 1 of window \"Control Centre\" of application process \"Control Centre\""
my doWithTimeout(uiScript, timeoutSeconds)
-- Click the “<fill in title>” button.
delay 1.017773
set timeoutSeconds to 2.0
set uiScript to "click UI Element 2 of group 1 of window \"Control Centre\" of application process \"Control Centre\""
my doWithTimeout(uiScript, timeoutSeconds)
on doWithTimeout(uiScript, timeoutSeconds)
set endDate to (current date) + timeoutSeconds
repeat
try
run script "tell application \"System Events\"
" & uiScript & "
end tell"
exit repeat
on error errorMessage
if ((current date) > endDate) then
error "Can not " & uiScript
end if
end try
end repeat
end doWithTimeout
Now the problem is that when I execute that script, in the second step it's not Screen Mirroring that's being clicked but Focus, the element above it. So somehow the line set uiScript to "click UI Element 6 of group 1 of window \"Control Centre\" of application process \"Control Centre\"" doesn't work as expected. I tried to replace the UI Element 6 with other numbers. Most of them result in a click on Focus, others turn off Bluetooth or AirDrop ...
How can it be that a recorded action yields a different result when played back? Any ideas?
I'm on macOS Ventura btw.

Edit: Solution for Ventura 13.0.1
After some testing on a Ventura VM, I found that a lot of stuff changed between versions so what I posted initially as a potential solution won't work.
In your script change set uiScript to "click UI Element 6 of group 1 of window \"Control Centre\" of application process \"Control Centre\""
to
set uiScript to "perform action 1 of UI Element 6 of group 1 of window \"Control Centre\" of application process \"Control Centre\""
Worked for me on Ventura (I just had to change the spelling of "Centre" to "Center") but that is probably because we might have different system languages set.
This other thread describes some of the changes on Ventura for this problem.
I've had a lot of issues with applescript and interacting with the Screen Mirroring item in the Control Center dropdown. As well as, trying to use Automator's record function to do something similar. The Screen Mirroring item in the Control Center dropdown is technically a checkbox so a "click" action should work on it but it doesn't for some reason. While the same "click" action seems to work on other items in the same dropdown like "focus" or "bluetooth". The issue also seems to exist on Big Sur and Monterey. I found that you need to "perform action 2" (Monterey) and "perform action 1" (Big Sur) in order to "click" on it from Control Center dropdown.
I'm not on Ventura but this works for me on Monterey.
set uiScript to "perform action 2 of UI Element 6 of window \"Control Center\" of application process \"ControlCenter\""
Things change between system versions so I had to remove the "of group 1" part to get this line to run on my system. Also had to change the spelling of "Control Centre" (not sure why spelling is different) to "Control Center" and removed the space in "Control Center" on the "of application process" part.
With your current code this might work. I changed the "click" to "perform action 2" and instead of selecting UI Element by number I used the name. I left the spelling the same of "Control Centre" though.
set uiScript to "perform action 2 of UI Element \"Screen Mirroring\" of group 1 of window \"Control Centre\" of application process \"Control Centre\""
It's possible that "perform action 2" might not even work on Ventura, as it changed from "perform action 1" on Big Sur so it could have changed again.
Here is a snippet of a working solution I have for Big Sur and Monterey. I have added a section that might work for Ventura. From what I gather from your code it looks like Screen Mirroring is inside a "group 1" which was different from Monterey.
Edit: This won't work for ventura
tell application "System Events"
tell its application process "ControlCenter"
click menu bar item "Control Center" of menu bar 1
tell its window "Control Center"
-- Monterey
if exists checkbox "Screen Mirroring" then
tell its checkbox "Screen Mirroring"
perform action 2
delay 1
end tell
else
-- big sur
-- "action 1" instead of "action 2"
if exists (checkbox "Screen Mirroring" of group 1 of group 1) then
tell its checkbox "Screen Mirroring" of group 1 of group 1
perform action 1
delay 1
end tell
end if
-- ventura??
-- "Screen Mirroring" is inside a "group 1"
if exists (checkbox "Screen Mirroring" of group 1) then
tell its checkbox "Screen Mirroring" of group 1
perform action 2
delay 1
end tell
end if
end if
end tell
end tell
end tell
I'm hoping not too many things have changed between Monterey and Ventura and it'll work. Run it from the system script editor to test.
If you'd like to see my full example please go to github here. The script also is able to select a device from the Screen Mirroring dropdown.
I just got a solution working for Big Sur and Monterey about a week ago after much frustration and testing.
