It is only possible on Group creation but not on Group update.
We create a Group with e.g. 5 members and afterwards there have to be 200 members.
I have to add the members with 200 requests (https://docs.microsoft.com/en-us/graph/api/group-post-members?view=graph-rest-1.0&tabs=http).

Thank you for requesting this, it is in our backlog, but we currently don’t have it planned in a sprint so cannot indicate target release to beta. ^JT
