Google gives the ability to add a group to another group.
For example, if we add Group A to Group B and user email@example.com is present under Group A, and when I try to retrieve the groups of the user firstname.lastname@example.org using OAuth 2.0 using the API https://www.googleapis.com/admin/directory/v1/groups, it returns only Group A, and not Group B.
I would like to get Group B too in the response from Google, since Group A is a part of Group B.
Is there any way to do this? Does Google provide us with the list of all parent groups as well in OAuth?
