You can configure the Discord Bot settings from the Dashboard > Settings > Discord Bot page.
Server ID: The ID (Guild ID) of the Discord server the bot is connected to. Clicking the “Remove Bot Connection” button will disconnect the bot. You need to unlink the bot to connect it to another server.
Sync Username: Changes the Discord username of users to match their in-game username.
If you encounter the error “An error occurred while connecting to the Discord server.”, reset the API Key from the Dashboard > Settings > API page and try again.
