PlayCanvas hand tracking occluder

Hi everyone,

I am using this hand tracking project as the starter project for a ring demo using playcanvas,

https://playcanvas.com/project/1115012/overview/8th-wall-ar-hand-tracking

but I am not able to make the hand occluder appear like in the A-frame example (A-Frame: Hand Tracking | 8th Wall | 8th Wall) using <xrextras-hand-occluder> generates a hand occluder in your scene.

Any help would be appreciated, Thank you!
