Skin issues with Spine

I am using Spine for my 2D art. I have a problem though. I need to toggle between 2 skins for one of my enemy sprites like so:

I wrote the code that toggles said skin,

 public class EnemyBehavior : MonoBehaviour {
     
     public GameObject enemy;
     
     //Reactions between rock enemy and player
     void OnCollisionEnter2D(Collision2D other)
     {
         Debug.Log("enters");
         if (other.gameObject.tag == Constants.Player)
         {
             enemy.GetComponent<SkeletonAnimator>().initialSkinName = "Alert";            
         }
     }
 
     void OnCollisionExit2D(Collision2D other)
     {
         if (other.gameObject.tag == Constants.Player)
         {
             enemy.GetComponent<SkeletonAnimator>().initialSkinName = "NoAlert";
         }
     }
 }

It even shows in the inspector that the character's Initial Skin name changes but not the skin itself therefore the character is stuck on the first skin I assign it.

What I found out is that when I click on the Reload button at the upper right of the Skeleton Animator script the skin changes!

My question then becomes: is it possible to call the Reload button through code? And if so, how do I access it? Many thanks in advance!
