I am trying to get SharePoint User group permissions (Ex: Read, Contribute) based on the group name using SharePoint Rest API. My goal is to get the permission level of the group and disable features on our custom app based on the permission levels. I have tried the below url to get the group properties but couldn't get the permission level of the group. Could anyone please guide me on how to get the User group permissions.
