Cloudflare stream - videos have multiple audio files/languages

If I upload an mp4 with multiple audio streams with correct language meta data with Cloudflare create an m3u8 / mpd file with all the audio streams with correct languages?

Also, if we use the Cloudflare player, does it have the ability to switch audio languages?

Along those same lines, if subtitles are added in multiple languages, do those get included?
