Google Drive account\n\n2. Gemini API credentials (LLM access)\n\n3. Telegram bot for approvals + confirmations\n\n4. Twitter Developer Account & API credentials\n\n## Customising this workflow\n\n- Swap Google Drive with Dropbox, Notion, or Airtable as your source.\n\n- Replace Twitter with LinkedIn, Instagram, or multiple channels at once.\n\n- Expand Telegram approval flow to include team voting or multi-step review."
