Render to the Editor window camera from native rendering plugin?

I am somewhat familiar with the native rendering plugin and using it in runtime builds. But I have a scenario where I need to render something into the editor from a native plugin and I need it to show through the scene view, but I can't get it to work.

I tried adding a CommandBuffer to the SceneView Camera that calls the RenderFunction with IssuePluginEvent:

Code (CSharp):

1.        
2. m_CB.IssuePluginEvent(GetRenderEventFunc(), 1);
3. SceneView.lastActiveSceneView.camera.AddCommandBuffer(CameraEvent.AfterEverything, m_CB);
4.  

This works for getting the plugin to render through different cameras just fine. But it does not work for the scene view camera.

Anyone know of anything else I need to do or try?
