How to position the HUD text in the center of the viewport in VR

I try to center my HUD text using the viewport Size x/2 and y/2 according to other posts suggest, however, it didn’t work in VR case. An y easy way to set the position of my test always at the center of the screen even in VR mode?

Realize this is an old question, but wanted to check if you figured it out. I was doing some experiments with vr and huds, and found that u need to use 3d widgets or stereo layers. Hope this helps
