Can I get Talabat and Deliveroo orders on the same screen as my own?

Yes. That is what the delivery apps connection is for. An order from one of the online food delivery platforms becomes an ordinary order here: your next order number, your orders board, your kitchen screen. The line names the app and says the app took the money. Set it up under Settings, then Delivery & dine-in, then Delivery apps, and read the docs tab Orders from delivery apps first.
