VR Expansion Plugin

Hello,
I’m working on a VR project for 4 weeks now. Everything VR related was new to me.
2 weeks ago I found plugin and I’m trying to understand it step by step.

But now I’m stuck on the hand tracking. I can’t get it to work with plug in, in other projects it works perfect.

My left hand is how I’m holding my right hand in real life, but the orientation is completely wrong. Also the fingers don’t move.
From what I read here and on the website, should work.
I’m using the Oculus Quest 2.

Thanks for helping in advance!
