Microsoft Teams Bot - User cannot initiate conversation - botframework

Question

We have a sideloaded Microsoft Teams bot (called Axel), fully operational and running in production. The bot is able to send messages (including proactive), receive messages, etc.
However, users cannot initiate a conversation with the bot -- the bot MUST send a message first for it to work. I believe this is not expected / desired behavior. When searching for the bot in the search tab, we find it, but when clicking on its name nothing happens.
How can we make it possible for users to initiate conversations with the bot?
Edit: here is our redacted manifest.json file

Translation of scopes:
Receive messages & data from me
Send me messages & notification
Access profile info
Receive messages & data from users in channels
Send messages & notifications in a channel Access team information

Answer 1

Your bot only has the "team" scope enabled.
Open your manifest.json in App Studio.
Go to the Bots section
Click Edit
Enable the Personal scope
Alternatively, you can just add the scope manually, then re-sideload/publish your bot.

}
Also, be sure that you've enabled the Teams Channel by going to:
Azure Portal
Your Resource Group
Your Web App Bot or Bot Channels Registration Service
Channels
