Hello!
I've ported this from VRTK to OpenXR and unity's XR interaction toolkit.
It works on my Vive Focus 3 (standalone android) and should work on any OpenXR compatible headset (almost all)

Also upgraded to Unity 2021 LTS and fixed a small bug when songs wouldn't play on some device.

Would love to contribute it back if this is something you intrested in.
