How to get my app content on Siri Search Results?

This question has been asked several times with no answer. I even opened a ticket with Apple and got no info. How do I provide a list of all the content (movies, tv episodes) for universal search so that a tvOS user can use Siri to search for content and our content will appear? Why is this so secretive?
