I already have a working eldorado.gg bot that logs in through a custom Chrome extension, grabs the session cookies, automatically places an offer on every new order request, then pops open the buyer’s chat window. The last missing piece is for that same flow to fire off a welcome message as soon as the chat opens. Here’s exactly what I need added: • A single, general-purpose welcome line (no user-name merge tags) that briefly introduces my services. • The message must post only once per order, immediately after the bot opens the chat, without duplicate sends on refresh or reconnect. • Everything else in the current script should stay untouched: cookie grab, offer placement, and chat opening are all stable. The project is written in Node.js with Puppeteer controlling a headless-Chrome context, so sticking to that stack is ideal. If you prefer a different automation library that achieves the same result reliably, I’m happy to consider it as long as the final hand-off includes clear setup instructions. Deliverable: updated, well-commented source that drops straight into my repo and sends the welcome message exactly as described, plus a brief README noting any new environment variables or permissions required.
