Jumping off moving platform in opposite direction

Hello! I have created a moving platform. It has as RigidBody attached to it, and is set to IsKinematic. It also has a PhysicMaterial, where the static friction is set to infinity, which prevents the player from sliding on the platform when it turns direction. This works fine.

Now to the problem: if I jump off the platform when walking in the opposite direction as the movement of the platform, my player sort of halts in the air. I believe this is physically correct, but not what I want in my game.

Is there any way I can make the player keep his momentum when jumping off in the opposite direction?

You have to add the reverse direction of the platform to the playermovement
