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?

まず、issue で言及されている README と Samples を確認し、次に Python SDK が Graph エンドポイントへのリクエストをどのように公開しているかを確認します。任意のエンドポイントがサポートされているかを文書化し、SDK API によって表現されていない reports/getTeamsTeamActivityDetail のようなエンドポイントを呼び出して処理する方法を示せば完了です。
