[Fixed] Quest 2, Hand tracking within VR Preview / PCVR not working

Hello, 
I am building a prototype using Lumen and hands tracking V2. 
I can not figure out how to see hands in VR preview or windows build / PCVR.

For now I am running Ue5.2.1, I am able to build for Quest 2 and Hands are working. ( the Hands Interaction train sample works well )

However with the same project, I can not see my hands in VR preview...

1 . I have my developer account and I've allowed OpenXR Extensions Through the beta tab in oculus APP "developer Runtime feature"
2. Meta XR API is set to "OVRPlugin+ OpenXR backend"
3. I have tried several combination of Pawn, with or without skeletal meshes,
Root
      |__Camera
      |__LeftMotionController
      |      |__LeftOculusXRhand ( set with mesh and skeleton to left )
      |__RightMotionController
      |__RightOculusXRhand ( set with mesh and skeleton to Right)

none works in vr preview.

Im I missing something? is there anything to factory reset for it to work?
Anyone from MetaStoreHelp could give us an hand? ( 😛 )

The plugin I am using is MetaXR 57.0,  MQDH 4.2, Oculus App Version 60.0.0.162.352

thanks!
