In the official documentation there is an example to make a DELETE request in order to delete a member from a group. Here's the documentation

DELETE https://graph.microsoft.com/v1.0/groups/{group-id}/members/{directory-object-id}/$ref

So far from what i've found and tested, when adding an user to a group, you can add up to 20 users per request, into a group

I was wondering if there is any possibility to remove multiple users from a group per request, or if you could remove 20 users at a time from a group, per request, like you can do when you're adding them into a group.
