I am trying to set up the E5 program and start doing some integration with my app. One feature of my application is it should be able to upload files to a Teams channel in Teams. While I was able to grant permissions on the development account to create teams, channels and retrieve information. I could not figure out how to enable Microsoft Graph to query the drive.
For instance,
I am trying to call this API
https://graph.microsoft.com/v1.0/groups/{my group id}/drive
and, I always get the error "serviceNotAvailable".
I tried contacting Microsoft support and they said I have a developer account and they can't provide support to me, sad. Does anyone know if there are special permission I need to set up in azure portal or anywhere to enable the Drive APIs?
