Thanks for the response! I was mistakenly looking at the docs in the manner that I needed to use the Twitch user’s authentication credentials to interface with chat (instead of an IRC user that can be a part of multiple channels).
For sanity -
Once the bot is authenticated, the Twitch user can add the bot to their chat (my server calling JOIN) and if they want to turn it off, remove them from chat (using PART command).
Thanks again!
