Improve the UI to not make items look like they are not selectable
If you to into User Management and select a single user, the UI makes it look like I can’t change a name or email, and I can’t. However, it also looks like I can’t change the permission level (Full Administrative and Selected Permissions), and I can. This bad selection of states is present across the entire app. You really need to do a review and fix the UI so that it is clear what I can change and what I cannot.
