How can I make a finger-interactable slider knob as VRC item?

How can I make a slider knob like the below color slider knob in Gorilla Tag, as a VRC item?

if I wasn’t making this for VRC, I would write a custom script to listen for collisions with the fingers and the slider knob. Then take the direction of the force and move the knob either up or down. But it seems like I cannot use this approach in VRC

It seems like there’s no way to get the direction of the force with PhysBones / PhysCollider.

VRCContactReceiver can be used to implement simple buttons that can be pressed down. But Im out of ideas for slider knobs.

I know of this free one, GitHub - Janooba/immersive-interactions: This project aims to provide the most comprehensive and physically accurate buttons and switches on the VRChat market..
Its somewhat close to what u want so sure there is a github out there somewhere for what u need.
