How to use the SDK to write Graph calls that aren't provided by the SDK API

Ahoi,

first, thanks for the SDK. It makes life easier and helps me to stay in the python eco-system for such tasks.
Now, I'm not really understanding Graph or the SDK well enough to see how I could write my own queries.
For example, I'd like to call the reports/getTeamsTeamActivityDetail(period='D90')?$format=application/json endpoint. As I don't see it in SDK 1.0.0a12, I'd like to "manually" call it and process the results.

Is this even feasable? Please excuse me if this call actually is in the API and I just didn't see it - take it as an example.

Is calling arbitrary endpoints even supported? Did I miss this when reading in README / Samples?

Inizia esaminando il README e i Samples menzionati nell’issue, quindi verifica come il Python SDK espone le richieste agli endpoint Graph. Il lavoro è completo quando documenta se sono supportati endpoint arbitrari e mostra come chiamare ed elaborare un endpoint come reports/getTeamsTeamActivityDetail quando non è rappresentato dalla SDK API.
