Playing one animation after another through Animator Controller

Hi, I have a prefab which has a Animator component and what I'm trying to do is to play one animation after another one.

Specifically, my character walk from point A to point B and, according to a condition, he has to stop and another animation has to play before he starts walking again.

This is my code so far:

 public class PlayerStreetCharacter : MonoBehaviour {
 
     [SerializeField]
     private float _velocity;
 
     [SerializeField]
     private Transform _baker;
 
     private Animator _animator;
     private SpriteRenderer _spriteRenderer;
 
     private bool _isSelling;
     private int _state; /** 0 (idle), 1 (walking), 2 (restless) **/
 
     private Vector3 _startPosition;
     private Vector3 _endPosition;
 
     private void Awake()
     {
         _animator = GetComponentInChildren<Animator>();
         _spriteRenderer = GetComponentInChildren<SpriteRenderer>();
         
         GameObject waypointsList = GameObject.Find( "BakerWaypoints" ).GetComponent<WaypointManager>().GetStallWaypoints( StreetList.Instance.CurrentStreet.ID - 1); 
         Transform[] waypoints = waypointsList.GetComponentsInChildren<Transform>();
         _startPosition = waypoints[1].position;
         _endPosition = waypoints[2].position;
 
         _baker.position = _startPosition;
     }
 
     private void Update()
     {
         Walk();
     }
 
     private void Walk()
     {
         _spriteRenderer.sortingOrder = (int) (-transform.position.z);
 
         transform.position = Vector3.MoveTowards(transform.position, _endPosition, _velocity * Time.fixedDeltaTime);
         
         WalkingDirection( _endPosition );
         
         if ( ( _endPosition - transform.position ).magnitude <= 1 )
         {
             Vector3 temp = _startPosition;
             _startPosition = _endPosition;
             _endPosition = temp;
 
             CheckingSells();
             
             if( !_isSelling )
             {
                 StartCoroutine( Restless() );
             }
         }
         else 
         {
             _animator.SetInteger("State", 1);        
         }
     }
 
     IEnumerator Restless() 
     {
         _animator.SetInteger("State", 2);
         yield return new WaitForSeconds(2f);
     }
 
     private void WalkingDirection( Vector3 position )
     {
         Vector3 dir = ( position - transform.position ).normalized;
         if( Mathf.Sign( transform.localScale.x ) != Mathf.Sign( dir.x ) )
         {
             Flip();
         }
     }
     
     private void Flip()
     {
         Vector3 scale = transform.localScale;
         scale.x *= -1;
         transform.localScale = scale;
     }
 
     private void CheckingSells()
     {
         GameObject clientWaypoints = GameObject.Find( "ClientWaypoints" ).GetComponent<WaypointManager>().GetStallWaypoints( StreetList.Instance.CurrentStreet.ID - 1 ); 
         Transform[] waypoints = clientWaypoints.GetComponentsInChildren<Transform>();
 
         _isSelling = true;
         for (int i = 0; i < waypoints.Length; i++)
         {
             Waypoint waypoint = waypoints[i].GetComponent<Waypoint>();
             if ( waypoint != null && waypoint.IsEmpty )
             {
                 _isSelling = false;
             }
         }
     }

The problem is that I can't see the Restless animation be played anyway. I would like to start an animation just when the other one finish. But using the Animatior component. I don't how is the correct approach to do that. I've been searching and didn't find a solution that works for me.

This is how my character is defined:

Thank you.
