Using the supported security questions

If I list all the supported security questions, they will come as objects with both a text (translated to whatever language) and something looking like a question short ID like “favorite_movie_quote”.

Now I can either set the question text or that ID thing. Which one should I use? The experience says whatever I set, THAT will be returned. If I set an english text, regardess the user locale the question will be english. If I set the short ID, that “favorite_movie_quote” will come back. No question text, just the ID! So looks like that ID was interpreted as a custom question text…

What I expect is: to set the question ID, and have Okta servers answer with properly translated question texts, depending on the locale (I still don’t know how to set the locale for calls, but that’s another question)
