CharacterCustomization AssetBundles

I got everything to work, and I have a script so I can build the bundles for Android.

 using UnityEditor;
 using UnityEngine;
 using System.Collections;
 
 public class ExportResource : MonoBehaviour
 {
     [MenuItem("Signature Creative/Build AssetBundle From Selection")]
     public static void ExportRes()
     {
         // Bring up save panel
         string path = EditorUtility.SaveFilePanel("Save Resource", "", "Package", "unity3d");
         if (path.Length != 0)
         {
             // Build the resource file from the active selection.
             Object[] selection = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
             
             BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets, BuildTarget.Android);    
             Selection.objects = selection;
         }
     }
 }

The problem is: When Unity created the entire example for us, they did NOT use: BuildTarget.Android in the BuildAssetBundle method. How could I find their prefabs so I can rebuild the assets for the platforms I want?
