Adobe Animate VR on Headset

I can post animations to a server but when viewing on a headset (Oculus Quest) in Firefox VR or Oculus Browser there is no option to Enter VR. Am I missing something? Is there something I need to add to the file for it to be recognized?

Thanks for any ideas or help, coulnd not find anything and even the tutorial samples when viewed in headset are flat.
