- Sync your Twitch account with your Discord account, by going into User Settings > Connections > Twitch.
Discord will automatically sync with your Twitch account, and you'll find all the streamers you're subbed to right in the Connections tab! You can hit the "Join Server" button and you'll get your special sub role, just like that.
Note that your special sub role may take upwards of 15 minutes to sync
