How can I change the translation language in-game?

I was wondering if it was possible to change the language in-game.

I tried with OS, and I think you need to access the Translation you need to change and use set_locale() on it? Anyway, thanks in advance.

Like this:

TranslationServer.set_locale("en")

AFAIK this won't change the translation in scenes which are already instanced/loaded.

Thanks! That was just what I needed.
