Stop player rotation when there is no movement

I want to stop my character from rotating with the camera when the character is still. I am not sure what the best way to go about it is. In my character controller I am using the new unity input system and for camera I am using Cinemachine, on my character I have the character controller component.

Here is the rotation code:

// Rotate towards camera direction
float targetAngle = cameraTransform.eulerAngles.y;
Quaternion targetRotation = Quaternion.Euler(0, targetAngle, 0);
transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);

and here is the movement code:

Vector2 input = moveAction.ReadValue<Vector2>();
Vector3 move = new Vector3(input.x, 0, input.y);
move = move.x * cameraTransform.right.normalized + move.z * cameraTransform.forward.normalized;
move.y = 0f;
controller.Move(move * Time.deltaTime * playerSpeed);

You could make a Vector3 field _lastInput or whatever and store your input in the movement function.

then in your rotation function just add

if( _lastInput.sqrMagnitude == 0 ) return;

at the beginning. That should do it.
