Show List<> in EditorWindow? [C#]

I’m trying to make an EditorWindow that has a List<> on it. But I can’t figure out how to do it. I have my List<> in another class that derives from MonoBehavior and I’m not really sure how to call it onto the EditorWindow.

I am not the most experienced with Editor code, but I believe you can use SerializedProperty and EditorGUI.PropertyField for this. The way I understand it, it will render the property as if it is serialized, which Lists can be. Just an idea to get the ball rolling. @Fritsl
