Nice! It works.
But the avatar was not aligned with the real person, do you have any tip to fix that?

Other than your headset's native tracking, alignment is 100% based on the anchors. There is a bug in which the anchor points are not the center of the controller ring, so direction matters. Try re-anchoring both devices, placing the controller rings in exactly the same spot with their triggers pointing the same direction.
