🔧 How it works: Telegram Trigger – Captures incoming messages from users on your Telegram bot

Langchain AI Agent (OpenAI GPT) – Interprets the message and uses RAG (retrieval-augmented generation) techniques to craft an answer

Google Docs Tool – Connects to and retrieves context from your specified Google Doc (e.g. FAQ, SOPs, policies)

Memory Buffer – Keeps track of recent chat history for more human-like conversations

Telegram Reply Node – Sends the AI-generated response back to the user
