How to get an array inside a simple class at Editor window and change arraysize?

Hello, guys! I hope you are fine in first!!!

Well, I have a simple script to show some arrays of GameObjects on my Custom Window, and I use SerializedObject to show array "enemies" with OnGui:

 EditorGUILayout.PropertyField(enemiesProp, true);

So far, it's OKAY, But I need to know how to get the array "heroes" inside World class and transform it in new SerializedObject like enemiesProp and set arraysize to 1 (and if it is possible).

My idea is: when the Editor Window opens for first time, we set the array "enemies" with 1 in size and populate th array heroes with 4 empty GameObjects

The current code works and set enemies size to 1 on opening, but I can't add the 4 GameObjects, I don't know to access heroes array and refresh on opening alt text

 using System.Collections.Generic;
 using UnityEditor;
 using UnityEngine;
 
 public class myClass : EditorWindow
 {
 
     [MenuItem("Tests/My Class")]
     public static void ShowWindow()
     {
         EditorWindow.GetWindow<myClass>("Test Window");
     }
 
     private SerializedObject so;
 
     private SerializedProperty enemiesProp;
     private SerializedProperty heroesProp;
 
     [System.Serializable]
     public class World
     {
         public List<GameObject> heroes = new List<GameObject>();
     }
 
     public List<World> enemies = new List<World>();
 
     void OnGUI()
     {
         //Show "enemies" field and set 1 to initial size
         EditorGUILayout.PropertyField(enemiesProp, true);
         enemiesProp = so.FindProperty("enemies");
 
         //Show "heroes" field and set 4 on size
         //?
     }
 
     void OnEnable()
     {
         so = new SerializedObject(this);
         enemiesProp = so.FindProperty("enemies");
 
         // heroesProp = ????
     }
 }
