Meta XR interaction SDK Essentials Hand Tracking on PICO 4 Ultra

Hello everyone,

Headset: Pico 4 Ultra
Unity: 2022.3.49F1
Meta XR Interaction SDK Essentials 69.0.1
Pico OpenXR plugin 1.3.3
Unity OpenXR Plugin 1.12.1
XR Interaction Toolkit 2.6.3
Xr Hands 1.4.3

I try to test the new version of the SDK interaction for non Meta headset, it works very well with the controllers.

When I want to go to the hands tracking, it appears well, the position follow up is ok, but when I close my hand nothing happens, no animations ???

In Project Settings, XR Plug-in Management, OpenXR, I put the Hand Interation Profile and in All Features, I have the hand tracking substystm, pico openxr features and pico support activated.

I really don't see what I forgot to do? Thank you in advance for your answers

- Edit : 

If I deactivate the prefab unityxrcontrollerhands and let unityxrhands activated in unityxrcameraiginteraction, hand tracking works.

Apparently, does that manage to properly pass controllers to hand tracking in an application?
