Community Test Chambers in VR don't work?

[Hypnoctopus]

I am able to play the Portal 2 campaign in VR (Quest 2 via USB to PC with Quest Link + Steam VR).

However, when I navigate to the Community Test Chambers and select one of my already published single player test chambers, it shows the typical loading screen (just like before the campaign loads in VR), but then it brings me back to the Steam VR virtual space.

Are community test chambers not supported with Portal 2 VR?
