I cannot find a way to add new translations to the genres retrieved by the API calls:

• https://api.themoviedb.org/3/genre/movie/list
• https://api.themoviedb.org/3/genre/tv/list

It seems that translations were managed with something called www.localeapp.com or app.localeapp.com that doesn't exist at the time.
Does anybody know who is in charge of this kind of changes now or how to do them?
