make it possible to use "m365 owner" group to set permission
When managing permissions for a modern SharePoint site you can actually use the m365 members group to add to a SharePoint permission group. But you can not add the m365 owners group.
The strange thing is when creating a new SharePoint Team site with a m365 group the m365 owners group is set by default on the owner permissions. But when you create your own owner groups you can not use/find the m365 owner group. The m365 member group can be found and can be used.
