Hi,
is it just possible to add/install the bot on the desktop app?
If I use the link in ios mobile app I get the notification that it can just be done in the web or desktop app.
If I add the bot app in ios mobile app via "more" I get the message "You have locked messages in this chat". This chat does not appear in web or desktop app.
If I open the app on web app (add further apps) I am not able to send messages. "You can not send Messages to this Bot". This chat does not appear in the desktop app or I get the app window with function "update".
If I open the link via deskop app I get the app windwo with function "add" and it works on all apps.
I think this is what you are looking for: Solved: Make bot available in iPad MS Teams app - Power Platform Community (microsoft.com)
Note: At this time, adding apps can only be done from the web and desktop versions of Teams. However, once you set up notifications or bots, they work just the same on your mobile device as on desktop. And, many of the apps you've added to tabs will appear at the top of a channel under More. App availability in mobile tabs varies by company that created the app.
