Trying to expose Custom Event from Scriptable Object

Hi! I am trying to expose a Custom event from a scriptable object so I can bind the creature effects to the creature assets in the inspector, and I am not being able to get the methods listed in the script I am attac$$anonymous$$ng, here are the points - 1 Scriptable object from w$$anonymous$$ch I created the asset, - 1 custom event class is done, - The custom event is exposed, I have the effects class w$$anonymous$$ch contains the effects for each creature now I want to bind those methods to the event in the inspector of the specific creature.

but I can't seem to get t$$anonymous$$s 1 part to work Any suggestion would be helpful.

MY Codes t$$anonymous$$s is the event class very basic

 [Serializable]
 public class CustomCardEvents : UnityEvent<bool>
 {
 
 }

editor code

 public SerializedProperty ActionEvent;
 
     void OnEnable () {
         //ActionEvents
         ActionEvent = serializedObject.FindProperty("ActionEvents");
     }
  public override void OnInspectorGUI() {
         serializedObject.Update ();
 EditorGUILayout.PropertyField(ActionEvent);
         serializedObject.ApplyModifiedProperties ();
     }

my custom class code(the script i am attac$$anonymous$$ng)

 public class myCustomEvents : MonoBehaviour
 {
     [SerializeField]
     public CustomCardEvents onChangeEvent;
     public bool effect(int a)
     {
         return true;
     }
 }

scriptable object code

 [CreateAssetMenu(fileName="New Card", menuName="Card")]
 public class Card : ScriptableObject
 {
     public CustomCardEvents myevents;
     
     [Header("General Info")]
     public Rarity rarity;
     public string id;
     public Sprite art;
     public Material material;
     public new string name;
     public Families family;
     public CardType type;
     public string ability;
     
     [Header("Creature Stats")]
