XR not working in godot-mono

Hello!

I'm running `extra/godot-mono` and encountered an issue that's not reproducible with the official binary. When trying to launch an OpenXR-enabled project with SteamVR running, Godot shows an error about not detecting any HMDs.

Re: XR not working in godot-mono

I made an account just to echo this issue. I'm still fumbling with setup, personally, but I think we can iron out some details.
- Are you enrolled in any of the SteamVR beta branches?
- Which headset are you using?
- Are you using ALVR?

My flow is: wireless Quest 3 > ALVR Client > ALVR Server > SteamVR stable as OpenXR > application.  All of my Steam games work, but Godot doesn't play.

Now that I say that, it may be worth installing the Steam version of Godot. 
Update Edit: Switching to the Steam version of Godot fixed this for me. I did not explicitly download a plugin, but it may have been included in the massive 1.8GB(!) Steam version of Godot. I would like to see a FOSS solution, but sometimes the ol' proprietary "It Just Works" comes in handy.

Some people have reported luck with the Godot OpenXR plugins. I will be trying this OpenXR Vendor plugin for Godot 4.3, but here are the OpenXR plugins available.
