Note that being a twitch partner doesn't give you monetary benefits or a better share from bits (one-time-"donations") or subscriptions. It only gives the streamer/community a verified profile and more emojis. So perhaps some more visibility on the start page but that's it.
The big music streamers will often stream on Twitch, Instagram, and FB all at once. Looks like Instagram is fine but FB has a desktop client and may not be allowed.
