Instagram’s live mode already allows people to watch a user’s live stream and send comments or hearts. With the latest update, live streamers will get a request button on their page which will let their friends join a solo live stream.
Once the request is accepted, the screen will be split into two parts.
Only users you follow back will be able to send a request to be in your stream. Also, a user can only invite someone who is already viewing your live video.
A user can leave your friend’s live video at any point in time. So it is easy to join a live stream for a quick hello or a longer chat. Similarly, a live streamer can easily remove or add a guest at any time.
