🌟 Key Features
Unified Messaging:** Receive and normalize messages from both Telegram (via Bot Trigger) and WhatsApp (via Webhook).

Process Response: Cleans formatting, identifies intents (order, appointment), and sets escalation flags.
Platform Router: Routes reply to the appropriate “Send Telegram” or “Send WhatsApp” node.
Log Conversation: Appends each message and response to the “conversations” sheet.
Update Customer: Increments previousOrders, updates last interaction timestamp, and saves a snippet of the latest message.
Escalation: If flagged, posts a formatted alert to your Slack channel for immediate attention.
