How do you use WhatsApp Business to take orders and send the menu?

An order comes in as a message with today's menu and is confirmed in the same chat, with a pickup or delivery time. Opening WhatsApp Business with nobody to answer during the shift means the order goes cold and the guest calls somewhere else. You need today's menu as a readable image, the minimum order if there is one and the neighbourhood you actually deliver to. The catalogue shows dinner dishes and at two in the afternoon a guest orders one the kitchen will not send. A message with the current menu, short replies for pickup or delivery, and an order note the floor sees when the shift starts.
