*Steps to reproduce:*

1. Create a new project in Unity 2023.2 using AR Mobile Template.

2. In Build Settings, change target platform to iOS or Android

3. In Game view, set {_}Play Maximized{_}.

4. Verify that _Project Settings > XR Plug-in Management > Desktop_ is set to {_}XR Simulation{_}.

5. Enter Play mode. 

6. Click the Options Menu button in the upper right corner to invoke the Options Menu. 

*Actual results:* 

The Options Menu is clipped off the bottom of the Game View window; the AR Debug Menu entry is not visible on the screen. 

*Expected results:* 

The Options Menu should either fit entirely on screen, or it should have scroll bars.  Either way, all Options Menu entries should be visible, i.e. the AR Debug Menu entry. 

*Reproducible with versions:* 

Unity 2023.2.10f1
com.unity.template.ar-mobile (Branch: release/2023.2, Commit: 6acf70d6)

*Not reproducible with versions:* 

*Can’t test with versions:* 

*Tested on (OS):* 

Mac Mini - M1, MacOS 14.3

{*}Notes:{*}{*}{*}
* Some of the menu entries on iOS and Android phones are so small that they are difficult to select, while in XR Simulation they are so big that this menu is clipped off the bottom of the screen.  There may be opportunities to eliminate Tech Debt here.  
* The only reason this does not occur with _Built Target = Desktop_ is that it is masked by [XRART-12|https://jira.unity3d.com/browse/XRART-12]. With Desktop build target the Options Menu button is missing, so the Options Menu cannot be invoked at all.
