I want to retrieve the users that belong to a specific group.
The request I'm trying to make is described here: https://cloud.google.com/identity/docs/reference/rest/v1/groups.memberships/list
For the parent parameter I use groups/{my_group_id}.
groups/{my_group_id} is found by using Method: groups.list
However, when I execute the request via the graph explorer it returns a 403 Error.
