Comment (by joyously):

 > `current_user_can()` does not work with AJAX

 That's a broad statement (AJAX is generic). If you use the REST API, you
 have to do authentication differently than if you use an ajax_action hook.
 The ajax_action hooks will only work from the WP site because of the
 authentication cookies. Those ajax_action hooks can (and do in core admin
 pages) use `current_user_can()`.

 Could you explain a test case?
