Editor GUI Foldout header style customization

Hello. I'm trying to stylize EditorGUILayout.Foldout header for EditorWindow like below:

Please, help to do that "like button" foldout with buttons inside and arrows.
Now I have this (dark or light editor theme doesn't matter)

with the code:

 void DrawLevelFoldout(int index) {
     var element = Config.Levels[index];
 
     GUILayout.BeginHorizontal();
 
     Foldouts[index] = EditorGUILayout.Foldout(Foldouts[index],
       Config.Levels[index].Name, true);
 
     if (GUILayout.Button("Delete", GUILayout.Width(100))) {...}       
     if (GUILayout.Button("Up", GUILayout.Width(50))) {...}     
     if (GUILayout.Button("Down", GUILayout.Width(50))) {...}
 
     GUILayout.EndHorizontal();
 
     if (Foldouts[index]) {
       element.Name = EditorGUILayout.TextField("Name", element.Name);
       element.Background = 
         (GameObject) EditorGUILayout.ObjectField("Background Prefab", element.Background, typeof(GameObject), false);
     }
   }
