Steps to reproduce:

1.  Create a new Unity Project
2.  Install the Multiplayer Play Mode package from the Package Manager
3.  Navigate to Window > Multiplayer > Play Mode Status
4.  Observe the contents of the window

\\
Actual results: The Play Mode Status window is completely blank

Expected results: The window should display placeholder information, such as a message like "No play mode session active."

\\
Reproducible with versions: 1.5.0-exp.2 (6000.0.47f1, 6000.1.0f1, 6000.2.0a9)

Not reproducible with versions: 2022.3.61f1 (No "Multiplayer Center" window is unavailable)

\\
Tested on (OS): macOS 15.5 (Silicon M4)

Notes:

• A completely blank UI can be confusing to users. A simple empty state message or helpful action hint would improve usability
