How to recalculate collider bounds when i animate a 2d sprite?

As you can see i have a simple 2d sprite, but when i animate it, it does not update its collider.
I need it to update to make the walk animation look more realistic, is there a way to do that, or do i have to make my own custom scripts?
Btw, i’m making a 3d game, with a 2d player.

Never mind i just need to add multiple colliders to each bone on the sprite.
