SCIM and mapping to a 3rd party app

hello, got a SCIM question:

we have a 3rd party application we are hooking up to SCIM (call it AppXYZ). The group we want to put people into in AppXYZ is called 'Group1'. On the MS Entra side, the MS Entra group is called "Testing Users". When I setup SCIM, how do I map the MS Entra group "Testing Users" to the group inside of AppXYZ called Group1.

Note: I cannot change the name of the group in AppXYZ - it must be called Group1, no exceptions and the MS Entra user group must be called "Testing Users" cannot alter the name.

thanks everyone.
