How to make an object slippery and force u to slide down.

Hey guys.
I have a small problem in my Scene. My Colliders work fine but if i jump into a object i “stick” at it.
What i want is that my player model gets forced to “slide down”. For example like a CS:GO Surf Ramp. (I dont want to make an surf game like CSGO surf, but just that u mby know what i mean)
Im using a Character Controller for my player movement and mesh colliders.

Thank you for your help!
