I've been scouting around for a way to do this without any actual implementation but every single method I can find is just some jank form of controller emulation.. Supposedly, enabling "Developer Runtime Features" (requires dev account) will actually send the hand tracking data through link.. If this is the case (and I'm pretty certain it is because I don't imagine the OpenXR Toolkit guide to be out of date by that much), would it be possible to implement the new hand tracking feature on the Quest version of the game to the Steam/PC one?
