One-time setup: log in with the creator account(s) to get refresh tokens for the Discord bot.
Add https://miserable-nonmonarchistic-mirna.ngrok-free.dev/callback as a Redirect URI in your TikTok app (Login Kit).
Add https://thatguyai.javachip.dev/callback/twitch as an OAuth Redirect URL in your Twitch app (dev.twitch.tv/console).
Sign in as thatguy_silver. This powers go-live alerts, chat bot, moderation from Discord, sub roles and EventSub. The token is saved to the database — no restart needed.
Log in with Twitch (optional chat-bot account)
Use a private window signed in to a separate Twitch account if you want bot replies to come from it instead of the creator. Make it a moderator in the channel.
