i was learning about making a top-down game using a tutorial but the player rotation doesnt work

    private void FixedUpdate()
    {
        _smoothedMovementInput = Vector2.SmoothDamp(
            _smoothedMovementInput,
            _movementInput,
            ref _movementInputSmoothVelocity,
            0.1f);
        _rigidbody.velocity = _smoothedMovementInput * _speed;
        RotateInDirectionOfInput();
    }

    private void RotateInDirectionOfInput()
    {
        if (_movementInput != Vector2.zero)
        {
            Quaternion targetRotation = Quaternion.LookRotation(transform.forward, _smoothedMovementInput);
            Quaternion rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, _rotationSpeed * Time.deltaTime);

            _rigidbody.MoveRotation(rotation);
        }
    }

    private void OnMove (InputValue inputValue)
    {
        _movementInput = inputValue.Get<Vector2>();
    }
}

    private void FixedUpdate()
    {
        _smoothedMovementInput = Vector2.SmoothDamp(
            _smoothedMovementInput,
            _movementInput,
            ref _movementInputSmoothVelocity,
            0.1f);
        _rigidbody.velocity = _smoothedMovementInput * _speed;
        RotateInDirectionOfInput();
    }

    private void RotateInDirectionOfInput()
    {
        if (_movementInput != Vector2.zero)
        {
            Quaternion targetRotation = Quaternion.LookRotation(transform.forward, _smoothedMovementInput);
            Quaternion rotation = Quaternion.RotateTowards(transform.rotation, targetRotation, _rotationSpeed * Time.deltaTime);

            _rigidbody.MoveRotation(rotation);
        }
    }

    private void OnMove (InputValue inputValue)
    {
        _movementInput = inputValue.Get<Vector2>();
    }
}
