I'm trying to find a way to collect a list of movies/tv shows from a specific network (based on a region). So far, I've seen there is a way to collect such a list from the discover endpoint, but in the "tv shows" case I cannot request with parameter "region", and in the "movies" case, there is no "network" parameter. How can I make such a request? I've seen that in the website I can filter by ott_provider and country, but I cannot see in the API. Thanks in advance for your help!
