Display Popup action to get notification when ordering by remote client

Hello, Really a fan of Samba Pos!! it’s a magnificent software for a restaurant.

I am using a Tablet to take order by using the GQL modules, from the GQL tutorial i have set up my remote client, but i want my ordering process a little different.

i want a popup Display With a predefined message to show in the server side when a order is placed in the remote client. it will be very much helpful if someone give me a solution.

Broadcast message and setup a rule ro pick up on that and show whatever type of message you want.
Mapp to server and it will only action on that machine.

Is there any flow u can reffer to?
