MS Teams Bot SupportingCalls error

New Contributor

I followed the series of @Tom Morgan  ( to create an IVR Bot. When I upload the app to MS Teams and install it, I cannot call the bot. It appears that it does not support Calls, but I did check the box for SupportingCalls and the same thing was done in the Manifest of the app. 

Meanwhile, I did another sample with random AppId (it is not registered) following Microsoft official HelloWorld sample. When I switch between tabs, call/video/share screen signs appear. You can see it in the picture. 


Can someone help, please? Thanks

@Mohamed Sahbi  You must enable developer preview mode
