My client has a car dealership business and I built a chatbot for WhatsApp and Instagram using botpress where customers can select any car to buy. He has several employees and I want that whenever a chatbot user clicks on the button that he is interested in a car, one of the employees gets notified and then my employee can continue the chat in the bot. Please help me and guide me on how can i solve this problem and integrate it into WhatsApp and Instagram.
