Want to make a button that controls a function in zoho - zoho

Question

I want to create an automated email in Zoho Cliq that sends a message to everyone every morning. In the message there is a button that should call the sendMsg function.
How can I define the sendMsg function?
The idea is that by pressing the button another message should be sent back to me.
Thanks for the help
