AI-powered Telegram support bot with department routing

This automation template enables efficient AI-driven customer support in Telegram. The bot routes users to the right department (billing, tech support, returns), answers queries based on up-to-date documents, and maintains conversation context. Knowledge base updates automatically when new PDFs are added to Google Drive — ideal for SaaS and service-based businesses.

## Who it´s for
- Owners of Telegram bots seeking automated customer support
- Companies with technical support, billing, and return policy teams
- SaaS products using Telegram as a communication channel
- Admins who want to dynamically update knowledge bases via Google Drive

## What the automation does
- On receiving /start or department commands (/billing, /ReturnPolicy, /TechSupport), the bot activates user session in PostgreSQL
- When a PDF is added to specific Google Drive folders, it triggers text extraction, chunking, and embedding via Cohere
- Embeddings are stored in Pinecone under dedicated namespaces (e.g., ´billing´, ´return policy´)
- For user queries, the LangChain agent retrieves relevant context from the correct vector store and generates accurate responses
- Session ends and state resets upon /end command
