How to make a surface that a player slips off of?

I’m trying to create a collision sphere in a level that the player collides with but will slip off of if they jump on top of it.

I have tried setting a physical material that has 0 friction and overrides the “friction combine mode” to use the minimum friction but the player can still stand on it.

Any idea how I should approach this?

Character is not a physical object that can use standard physical interactions, so friction will not work in this case.

You must kinda simulate slipping. Try to use AddImpulse or AddMovementInput for this.
