🟢make_quiz(description, material, material_title, players, difficulty, ...)
Tjaz writes a multiple-choice quiz with its own AI from a description of what it's about, and the source material it's to be made from when there is any, for the people who will play it, and gives back a link to play it alone, in a 3D game or together on a big screen, and to share it. Use this when the user asks for a quiz about a subject, or from material they gave you, e.g. a chapter, their notes or a web page, and hasn't written the questions. Usually ready within a minute; if not, it gives the link where the quiz is being written, and get_quiz tells when it's ready. Tjaz writes it in the language of the description, unless language is given.
