Get all members of a group - transitive

问题

Is there a call to graph API that returns to me all members of a group - including the users of nested groups?

• To get all direct members for a group, there is GetGroupMembers
• To get all groups for a user transitively, I have found getMemberGroups

But I didn't find anything to get a list of all members, including subgroups (as in "if I send an email to group xyz, which users will receive it?").

Is there no such function available or did I overlook something?
