PassthroughHands Demo

Has anyone had any luck getting the PassthroughHands demo working from the Oculus Unity plugin? It seems that in order to use hand tracking you need the legacy LibOVR backend, but to use passthrough api you need the OpenXR backend. Considering there's a demo that seems to use both handtracking and passthrough, I'd think there must be a way to use both but I can't figure it out
