MS Teams - how the integration works

we need to find the documentation on the MS Teams integration.
we need NOT the documentation on the setup, but on how the integration works, for example:

1. to obtain the attendance file, is it necessary for the Instructor to remain connected for the entire duration of the meeting?
2. to obtain automatic completion, is it necessary for the Instructor to remain connected for the entire duration of the meeting?
3. on what basis is the presence of the participants calculated (attendance file)?
   is it calculated based on the time the Instructor stays in the meeting (closing the meeting - opening the meeting by the Instructor )?
