Checks conditions and either sends a default message or processes the message for content generation.\n3. Uses an AI agent to generate rich content including images and text.\n4. Formats and sends generated text in multiple languages over Telegram.\n5. Saves generated image data and logs it into a Google Sheet.\n6. Sends back image content to Telegram as a photo message.\n\n### Setup steps\n\n- [ ] Configure Telegram credentials for messaging services.\n- [ ] Set up OpenAI API access for content generation.\n- [ ] Connect to Google Sheets with appropriate API credentials.\n\n### Customization\n\nLanguage options for text messages can be extended by adding more language nodes."
