Hey there,
I've come across some new parameters in the Instagram API - "cover_url" and "audio_name". You can check them out here: https://developers.facebook.com/docs/instagram-api/reference/ig-user/media
The new parameters pertain to the reel type post. I haven't seen them in the Instagram for Business integration yet. Any chance you guys could update it to include these? It'd be a game-changer for automating reel uploads.
