Physics Assets Constraints missing?

I haven’t been dealing with skeletal meshes for quite some time. I think it was back in version 4.13. Where I clearly remember a little pink cross icon which would open a constraint editor for bones. I feel really, really stupid now. But I can’t find it in 4.25. I tried to google it, most tutorials seem outdated and refer to clicking on that cross icon. Which I can’t for the life of me find. So, yes I’m stupid, but how do you edit constraints in Physics Assets for a skeletal mesh?!

Its been changed since .18.
check the relative live talk for hands on examples.

In the tab with the items/bones etc. Right click and select show primitives, click again and select show constraints.
the new graph tab basically tells you what is connected to what.
