i'm wondering if this is a new feature from discord like, like a modal upgrade or something, and if we can use them now, what are the keywords i do with them
iframes are currently only available to midjourney (and potentially very select few premium bots in the future) and we do not know of any plans to open this up to a wieder public.
features this selective are usually given selective experimental documentation and do not lend themselves to implementation in a general api wrapper (unless it is opened to a wider public)
