OpenXR VR Handtracking multiplayer: Set skeletal mesh with hand key points


I am making a VR multiplayer application with handtacking.
I am not using the OculusVR handtracking because I need it for multiple devices.

The problem I am having now is that I can’t set a skeletal mesh to the key points I have.
I think this shouldn’t be hard but I can’t find it online. I am also pretty new to Unreal Engine.

So I have the location of every key point of each hand, now I just need to set the bones of my skeletal mesh to these locations.

Anyone that can help me with this? Thanks
