XR Grab and Unity joints issue

Hi, I spent weeks on VR Grab and joints to make my own lever / joystick with the XR Interaction Toolkit.

First method

Using this method : https://www.youtube.com/watch?v=bYS35_hC6B0 , when I grab a GameObject with both XR Grab interactable and a Hinge joint or a Configurable joint the GameObject : - tremble a little when moving it (it looks not stable at all) - teleport itself in random positions when my direct interactor move away while holding it.

Second method

Using this method : https://www.youtube.com/watch?v=3cJ_uq1m-dg , The joystick is very stable but is also very slow to look at my controller position when grabbing it. I couldn't find any way to make it more nervous / responsive.

I tried so many settings on physics and apply many approaches from tutorials but never achieve my original goal. I need joints because I need angular constraints to my lever ; and joints were pretty handy to compute lever output [0;1] depending on joint angle limitation range [-60°;60°].
