This step adds a buffer to help prevent issues when multiple messages arrive at once.)\n\n**3. Download Telegram Voice File**\n- **Node type:** `Telegram`\n- **Resource:** `file`\n- **File ID:**  \n"

Buffer Delay (Pre-AI Processing)**\n- **Node type:** `Wait`\n- **No parameters required**  \n  (Leave as default. This adds a small delay to ensure the transcription is fully complete before moving to the AI.)\n\n**6. Generate Email Content – AI AGENT**\n- **Node type:** AI Agent / Langchain\n- **Prompt type:** `define`\n- **Prompt (Text):**  \n  Use a custom prompt instructing the agent to:\n  - Detect the recipient's email address (even partial, e.g. \"send to fort.baptiste.pro\", and complete if needed)\n  - Understand user intent (resignation, request, excuse, etc.)\n  - Generate a suitable email subject\n  - Write a professional email in HTML (proper formatting, no spelling mistakes)\n  - Example variable:  \n    ```\n    {{ $json.text }}\n    ```\n- **Model:** Connects to the `GPT-4 Email Generator Model` node (OpenAI Chat Model)\n- **Output Parser:** Connects to the `Enforce Email JSON Schema` node (Structured Output Parser)\n- **Credential:** Your OpenAI API key\n\n**7. GPT-4 Email Generator Model**\n- **Node type:** OpenAI Chat Model\n- **Model:** e.g. `gpt-4.1-mini` (as in your template)\n- **Credential:** Your OpenAI API key\n\n**8. Enforce Email JSON Schema**\n- **Node type:** Structured Output Parser\n- **JSON Example/Schema:**  \n    ```json\n    {\n      \"email\": \"adresse@gmail.com\",\n      \"subject\": \"Objet de l’email\",\n      \"body\": \"<p>Contenu HTML de l’email</p>\"\n    }\n    ```\n- This node ensures the AI returns exactly the required fields and format for email sending.\n\n**9. Send Email**\n- **Node type:** Gmail\n- **To:** `{{$json.output.email}}`\n- **Subject:** `{{$json.output.subject}}`\n- **HTML Body:** `{{$json.output.body}}`\n- **Credential:** Your Gmail OAuth2 credential\n- This node sends the generated email to the intended recipient using Gmail.\n"
