How to use SkeletonIK nodes with certain constraints?

Basically, I want to use SkeletonIK for its intended purpose, but I want each bone to be constrained so it can only move along a single axis. Is this possible?

I think you have to create a physical skeleton. (Click you skeleton at the top of the screen in 3d view → create physical skeleton)
Then if you select a physical bone you can choose what type of joint you want and set constraints.
Last time I checked some joints hasn’t been working right in Godot4 though, don’t know if that’s resolved yet…

I tried that even with constraints it still didn’t work.

After I set up constraints and confirmed it they worked I added the SkeletonIK and then it just ignored the constraints.
