*Steps to reproduce:*

1. Use Unity 2023.2 to create a new project from AR Mobile Template. 

2. In Build Settings, Choose Desktop.

3. Project Settings > XR Plug-in Management > Desktop > XR Simulation. 

4. Enter Play mode. 

*Actual results:* 

The Build menu, Options menu, and Delete button are missing. Also, after clicking Continue on the Welcome UI, the hints UI does not appear.  See attached screenshot.

*Expected results:* 

Change Build Target to iOS or Android to see correct behavior.

The Build menu, Options menu, and Delete button should be apparent. Also, after clicking Continue on the Welcome UI, the hints UI should prompt the user to scan planes, spawn objects, etc.
