Open Monster Lab Simulator and navigate to the settings menu. Click on the Twitch Icon to begin the authentication process. This will open your browser.
Log in to your Twitch account if requested. Click Authorize to allow Monster Lab Simulator to read chat and cheering events for the simulation.
Once authorized, you will see a success confirmation (like the one on this page). Your Fulu names will now sync with your chat, and donations will trigger special events in your lab!
