Have you checked these in order to add ng-app

Do you have a specific use case that requires exposing the collector unauthenticated? or you are just testing out stuff?

I prefer to not expose the collector unauthencited but dont have a good alternatnive neither. If we add the telemetry to the angular app that needs to push it somewhere too?
