+        Updates a permission scheme. Below are some important things to note when using this resource:
+        - If a permissions list is present in the request, then it is set in the permission scheme, overwriting all existing grants.
+        - If you want to update only the name and description, then do not send a permissions list in the request.
+        - Sending an empty list will remove all permission grants from the permission scheme.
