The hand tracking support is actually an effort I have started even before NIS and the other stuff and that enabled me to learn how to make all those OpenXR tricks work.
As somebody else already pointed out there is a dedicated thread for it; here’s one of my replies with a quick demo of what it can do today:
Main issue is right now it needs a lot of tweaking in order to become more usable, because in the end what this does is piggyback on the VR controller support, and make the game believe that your hands are the controller. This comes with some challenges since hand interaction is quite different from controller interaction in some ways.
