Pilot's body oxygen tube

[gonvise]

Hi... I always fly in VR, and the addition of the pilot's body has been a turning point due to the realism and having the kneeboard at a glance. I don't know if this problem is exclusively mine and my quest pro, but I can't see the oxygen tube, in fact, I found out it existed when I forced my head forward and "suddenly" it appeared. On the other hand, when I move my head, the body also moves from one side to the other, I don't know if it's intentional, but it's not very real.
Does the same happen to you?
