New with UIElements in 2019 - How to draw default inspector

As title, I use Unity 2019.1 and try new UIElements. This feature can load UI from uxml. But how to draw default inspector? I tried DrawDefaultInspector() but it didn't work.

Code (CSharp):

1. public override VisualElement CreateInspectorGUI()
2.     {
3.         DrawDefaultInspector();
4.         var root = new VisualElement();
5.  
6.         var uxml = AssetDatabase.LoadAssetAtPath<VisualTreeAsset>("Assets/Editor/Test.uxml");
7.         var uss = AssetDatabase.LoadAssetAtPath<StyleSheet>("Assets/Editor/Test.uss");
8.  
9.         uxml.CloneTree(root);
10.         root.styleSheets.Add(uss);
11.  
12.         return root;
13.     }

 

I know you have probably found a solution to this already but I'm going to post this here for the other people who didn't.
You just have to add this 'defaultInspector' VisualElement to the root.

Code (CSharp):

1. IMGUIContainer defaultInspector = new IMGUIContainer(() => DrawDefaultInspector());
