Is it because you are expressing the claim as a group and not a role? Just comparing it to my own configuration. Does that match the Entra Claim type as those have to match as well so if it is group here then it needs to be group there.
We use Claim Type: http://schemas.microsoft.com/ws/2008/06/identity/claims/role
Looking at the 2 pics they do not match for claim type, so that’s probably it.
