How to calculate the resulting velocitys and rotation speed after two concave polygons collide in 2d

so I’ve been searching google for how to do this, but all anyone seems to care about is collision detection =p, and no results come close to teaching me how to calculate 2d elastic collision between two concave polygons.

I know how to solve elastic collisions between two 2d circles, but I can’t find anything more complicated than that.

I’m also a very visual person, so it would be great if someone could show me how to proceed
