You can use the Exclusive Content for Subscribers extension. This extension enables streamers to create content just for the subscribers on their Twitch channel page. The subscribers of the channel will be able to view members-only content that the streamer creates on his/her Twitch channel. All you have to do is visit the extension config page to create content with the content builder of the extension. The post will then be available in a panel on the streamer’s page for the subscribers to see.
