Welcome to the Make community!
Try using Roles instead of Groups?
To do this, you can try using the Google Workspace Admin “Delete a Role Assignment” module —
Deletes a role assignment.
For more information about the “Delete a Role Assignment” module and the Google Workspace Admin app, see the corresponding Integrations page and the Help Centre documentation.
Hope this helps! If you are still having trouble, please provide more details.
