For every new Solo Shuffle round out of 6, you and your team mates get a new unique key displayed by the ingame addon. Click it and copy (CTRL+C) it before the start of each round.
In Discord, click the ➡paste-shuffle-key channel, then the "Enter Key" button, paste your key and hit enter.
You now have access to a text and voice channel unique to your new shuffle team constellation.
