Pop-up notification Not Sent to Restaurants When Customer Places an Order

Describe the bug
When a customer places an order through the Enatega multivendor application's customer app, the restaurant app is not receiving any popup notifications informing them that an order has been placed. This lack of notification prevents restaurants from promptly acknowledging and processing orders, leading to delays in order fulfillment and potentially affecting customer satisfaction.

To Reproduce

Open the Enatega customer app.
Place an order from any restaurant.
Check the restaurant app for notifications regarding the placed order.
Note that no notification is received by the restaurant app.
Expected behavior
When a customer places an order through the Enatega customer app, the associated restaurant app should promptly receive a notification informing them of the new order.
