How to check if GameObject is moving sideways (left or right)?

I’m making my player strafe left and right not just one running animation for moving.
So to do that I want to know how to check if the player is moving left or right to add the animation easily.

public CharacterController controller;
public Transform groundCheck;
public LayerMask groundMask;

public float groundDistance = 0.4f;
public float speed = 12f;
public float gravity = -10f;
public float jumpHeight = 3f;

private Animator animator;

Vector3 velocity;
bool isGrounded;

void Start()
{
    animator = GetComponent<Animator>();
}

void Update()
{

    isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

    if (isGrounded && velocity.y < 0)
    {
        velocity.y = -2f;
        animator.SetBool("isGrounded", true);
        animator.SetBool("isJumping", false);
    }
    else
    {
        animator.SetBool("isGrounded", false);
    }

    float x = Input.GetAxis("Horizontal");
    float z = Input.GetAxis("Vertical");

    Vector3 move = transform.right * x + transform.forward * z;
    

    controller.Move(move * speed * Time.deltaTime);
    animator.SetFloat("speed", move.z);
    animator.SetFloat("xSpeed", move.x);

    if (Input.GetButtonDown("Jump") && isGrounded)
    {
        velocity.y = Mathf.Sqrt(jumpHeight * -2 * gravity);
        animator.SetBool("isJumping", true);
    }

    velocity.y += gravity * Time.deltaTime;
    controller.Move(velocity * Time.deltaTime);

}

if (move.x < 0f)
//moving left
else
//moving right
