How to Play ParticleSystem from AnimationEvent?

Hi

I'm trying to play a Particle System from an Animation Event.

I created the event on the animation clip and assigned the name of the function that I want to run to ShowMuzzle. For reasons unknown to me the Event its called but the particle never shows.

I even create an Editor Extension to invoke the method on PlayMode. When I use my custom button it gets called and the particle shows up, but when I use the animation event the particle is never shown.

Here is the Code of the ShowMuzzle Method:

 public class WeaponAnimator : MonoBehaviour, IWeaponAnimator
     {
 
         [SerializeField]
         private GameObject particleEmitorContainer;
 
         [SerializeField]
         private GameObject dropableModel;
 
         [SerializeField]
         private GameObject projectileSpawner;
 
         public GameObject ParticleEmitorContainer => particleEmitorContainer;
 
         public GameObject ProjectileSpawner => projectileSpawner;
 
         public GameObject DropableModel => dropableModel;
 
         public void ShowMuzzle()
         {
             foreach (var particle in particleEmitorContainer?.transform.GetComponentsInChildren<ParticleSystem>())
             {
 
                 particle.Play();
 
             }
 
             Debug.Log("MuzzlePlayed");
 
         }
     }

And here is my code for the Editor Extension to Call the metod:

 [CustomEditor(typeof(WeaponAnimator))]
     public class WeaponAnimatorEventRaiser : Editor
     {
         public override void OnInspectorGUI()
         {
             base.OnInspectorGUI();
 
             GUI.enabled = Application.isPlaying;
 
             var animator = target as WeaponAnimator;
             if (GUILayout.Button("Invoke Particle"))
             {
 
                 animator.ShowMuzzle();
 
             }
 
         }
     }

Any Idea on why the particle is not shown using the AnimationEvent?
