How to make all 3D GPU particles slide and align to normal when colliding?

Currently when colliding particles, 99% of them get stuck in geometry and don't slide or they either don't collide and skip collision. Using Particle Collision Box.

How to make them slide (like the second part of the GIF here)?
Is it also possible to make them align to the normals of the collision surface, like the second part of the GIF too?

alfredbaudisch in a fresh project it works 🤷 , then as can seen below, a part of the particles do not collide.

Solved by making the Box Collider thicker and wider.

Thanks to Hendrik Mans from Mastodon for the tip!
