Fetching user permission groups from sharepoint for a user using graph api

Question

Hi Team,
I have a set of user permission groups configured in sharepoint.

(1) Is there a way to fetch the groups in which a user is a member of?

(2) Is there a way to fetch the users in a particular group by group id?

(3) Also the 'groups' end point is not returning user permission groups. Is there an alternative?
