How to make a page at the front end of the server pop up a dialog box by calling the background interface

my requirement is: the Android side requests the background interface, and then the background interface makes the background management system page pop-up dialog box, how to achieve it?

as shown in the figure, the background interface is written in AdminOperatiions, and the management system page is home_admin

although your requirements are strange, you can do it by setting up websocket on the background management page.

is it just like sending a notice? check whether there is a notice when refreshing the page, click
, or do you want to be real-time?

server front-end page, or a front-end
this requirement is essentially two front-ends communicating through the server

Thank you for your answers. I solved this requirement through websocket
