The customer places an order from a restaurant (can’t place an order from multiple restaurants at a time)
The delivery boys get that order in the order request section and accept it for delivery.
After the delivery man’s confirmation (If turn on the delivery confirmation model), the restaurant owner gets the order on their dashboard and starts processing or cooking, and handover the items to the delivery boy.

If the admin turns on the store’s confirmation model, then for both case no need the delivery man’s confirmation but after restaurants, confirmation delivery men will get the order for acceptance.
The Delivery Guy accepts the order, confirms the order (if COD), picks up the order, and delivers the order to the Customer.
