You can use the [social_stream browser extension](https://github.com/steveseguin/social_stream#readme) to mix multiple chat source (from Peertube, Twitch, Youtube, Facebook, ...) and include their contents in your livestream.The compatibility with this plugin was added in recent versions.
In the "plugin settings" tab, there is a "{{% livechat_label use_chat %}}" checkbox.Just check or uncheck it to enable or disable the chat associated to your video.
On the instance level, Peertube's administrators can choose if chat rooms are unique per video, or if there will be an unique chat room per channel.Please contact your instance's administrators for more information on how they configure the livechat plugin.
{{% livechat_label read_only %}}: you will only be able to read the chat, not write. This is useful to include the chat content in your livestream (see the [OBS documentation](/peertube-plugin-livechat/documentation/user/obs)).
