How do you use a UOctreeDynamicMeshComponent?

I am working on building a procedural terrain and the UOctreeDynamicMeshComponent seems quite handy. The problem is that I see no apparent way to setup the FOctreeDynamicMeshSceneProxy SceneProxy, and so calls to things like NotifyMeshUpdated are doing nothing because the first thing it checks for is the presence of a SceneProxy, which remains a nullptr.
