Based on the exhibits provided:

The 'Remote-Client' is tagged as 'Remote-Users' in the FortiClient EMS Zero Trust Tag Monitor.

To ensure that the tag 'Remote-Users' is visible in the FortiClient GUI, the system settings within FortiClient need to be updated to enable tag visibility.

The tag visibility feature is controlled by FortiClient system settings which manage how tags are displayed in the GUI.

Therefore, the administrator needs to change the FortiClient system settings to enable tag visibility.
