I didn’t have much luck with VR controllers when I played around a while back, but I did notice they had generic XR controllers listed back then, have you tried to use those instead of the Oculus specific controller implementation?
Changing it to generic ones might allow the input to be picked up.
I couldn’t get the XR interaction system to work with the input system until I installed the XRInteraction Subsystems package.
Edit: It may not have been the the Interaction subsystems package.
Rather, I realized that the oculus controllers only take into effect AFTER CLICKING ON THE GAME WINDOW WITH YOUR MOUSE!
This is a very easy thing to miss if you are fumbling around with a headset as you probably can’t even see your own monitor when putting these darn things on!
