Physics Material 2D not showing up

whenever I try to add a new physics material 2d the option doesn’t show up. the only thing that shows is ‘Physic Material’ I’m using unity version 2020.3.1f1. and when I try to use the physics material that does show up, what happens is that I can’t use it on anything.

here is what i mean :

if you mean where is “Material 2D Physics”, it’s in the 2D option (2020.3.24f1)
