Hi ,
{ "User.Read", "Calendars.Read" } - Authenticates Successfully and able to get the access token.
{ "User.Read", "Calendars.Read", "Calls.JoinGroupCallAsGuest" } - Authenticatiom fails with following error message.
com.microsoft.identity.client.exception.MsalServiceException: invalid_client;AADSTS650053: The application 'myTeamCommunication' asked for scope 'Calls.JoinGroupCallAsGuest' that doesn't exist on the resource '00000003-0000-0000-c000-000000000000'. Contact the app vendor.
ragup83 You can't initiate a call with a user token. It's mandatory to make it with application permissions. You can create a web API that manage your calls and call the API from your android application. It also means that your call will be created with the bot identity. You need to manage redirection or transfer if you want to create a P2P call.
There is a specific SDK for that called Microsoft Graph Communications. You can find some documentation here https://docs.microsoft.com/en-us/microsoftteams/platform/bots/calls-and-meetings/calls-meetings-bots-overview and also an example here https://github.com/microsoftgraph/microsoft-graph-comms-samples/tree/master/Samples/V1.0Samples/RemoteMediaSamples

I have configured the delegate and Application permission for the registered application in the ADS. I can see only the delegate permission but not Application permissions in the access token.
I am able to authenticate and get an access token when I included the delegate permission in the scope list. If I add any Application permission in the scope list and call the SignIn method from Android application then it is failed.
