It's a very efficient way of keeping your stream chat within easy reach without the need to have a separate window open and is particularly useful to those who don't have the space or budget for a monitor dedicated to their stream chat. Open OBS and head to File > Settings > Stream > Twitch.

Navigate to Settings > Stream > Copy Primary Stream Key. Click your profile icon in the top right-hand corner and pick Creator Dashboard. OBS.Live does have some other neat features, too, including an activity feed and even music controls, but even if you only need Facebook Gaming chat, it's worth getting. Alternatively, you can sync Twitch with OBS using a stream key: Open a web browser and log in to Twitch. Simply download the plugin and authenticate your Facebook account, and you're set. Depending on how they are appearing in your stream, theyll need to click Add your Camera to OBS or Remote Screenshare into OBS. If you have Two-Factor Authentication activated, you will be prompted to input your security code in order to log in successfully. You’ll start by logging into your Twitch account. But even if you're not, it's free to use and will let you have a Facebook Gaming (it supports Twitch and YouTube, too) chat window inside OBS Studio. After you have installed and opened the Twitch Studio app, you will go through the initial setup process. If you're using StreamElements for your alerts and overlays already, it's a no-brainer. The answer is StreamElements' OBS.Live plugin. But, despite having no popout chat feature on the website, there is still a straightforward way to get Facebook Gaming chat inside OBS Studio.
