Hehe. I have been writing up the same thing. Was adding some extra info and screenies 
When you need to run the app, you can use the camera in the scene as your camera source.
Also, in your main collection file, I usually use a Collection file - and then assign the sync tool collection you want to test/view into the scene. Its a little like referencing the asset. I recommend this, because then you can have one “project” collection with scripts etc, and you just add collection files as needed. There are some gotchas to this method, but its good for testing.
The github project includes a sample project and an orbit camera script to easily look at and test your generated assets.
Code to use:
I often use:
msg.post("/Collection/Camera#camera", "acquire_camera_focus")
