unity – How to stop sliding properly

I wanna stop immediately (not instantly) when I release a key so it would not slide. I don’t wanna use rb.isKinematic = false; because it’s just stopping so instant. So like I thought about:

x = GetAxisRaw("Horizontal");
z = GetAxisRaw("Vertical");

move = transform.right * x + transform.forward * z;

if (no inputs pressed)
   rb.AddForce(force * -maxSpeed); // maybe force will be the current velocity

I tried this but seems like nothing is hapenning. And so I think I need some improvements
