Google Sheet with two tabs. \"Участники\": id, name, email, tg_chat_id, source, registered_at, confirm_sent, r24_sent, r1h_sent, r10m_sent, attended, noshow_sent. \"Заказы\": order, email, name, offer, status, created_at, updated_at.\n2. Set the start time, room and recording links in both \"Settings\" nodes and the room link in \"Open the room\".\n3. Form or bot builder posts to /webhook/webinar-register: name, email, tg_chat_id (if the person came from the bot), source.\n4.
