How do you attach moving parts (moved by physics) to an animated character? (Secondary Animations)

I basically want to attach something like a sword sheath or a pouch to my animated character and when I move around I want the sheath to be affected by movement.
I’ve tried using hinges and joints but the objects I attached just stayed at the spawn point and didn’t follow the character. They were glitching around a bit when I turned but all in all they were just not moving.

I unfortunately was not able to find anything related to this.

Any help is greatly appreciated!

I’ve found the solution. I had to parent the objects to the skeleton and not the mesh itself.

Then I encountered jittering because my character controller was colliding with my joints, fixed using:

Physics.IgnoreCollision(collider1, collider2, true);
