You're absolutely right. Looks like I should have shut my mouth up twice in row, I stand corrected (with hot ego bruises ).
You will, however, grant me the discord capture was a little confusing, since it mentioned the Quest, not the Pro. The Quest lacks the required hardware for eye tracking, whereas the QP does, and definitely IS on OpenXR TK compatibility list (though with limitations), leading to my wrong assumption.
Anyway, sorry for the mess, please keep up posting your feedbacks on what could soon become my new VR HMD.
