Detect all groups from IdP for scoping

I thought I would not have to create a new group in the IdP, but rather select among the groups that were already created.
So, for us at M365 IdP, we have our groups created, for example:
XXX-HQ
XXX-Germany
So I expect that the integration would be able to fetch already present groups from the IdP and let us select from those groups.
With the current behavior, I would need to either rename XXX-HQ to Secfix-XXX-HQ or create another "duplicate" group called Secfix-XXX-HQ.
