interfaces , Java fx

The application (here) is a crisis management system involving police and firefighters who cooperatively intervene at the site of an “ongoing” crisis. The crisis management process consists of deciding on the dispatch of cars and trucks which police and firefighters monitor dispatch and arrival until the crisis is over. As it stands, the application does not have a human-machine interface. More specifically, a Java main program tests the chain of crises to roughly verify that the application as a whole is working. The work consists of building a human-machine interface in JavaFX * or in HTML, CSS and JavaScript / TypeScript. In the second case, we must use the WebSockets technology to push the data to be displayed from Java to the browser; the instructions then arrive in the opposite direction (examples of WebSockets programs are explained and available here…). This man-machine interface must allow connection as a police officer (Police Station Coordinator) or as a firefighter (Fire Station Coordinator). Once logged in as a police officer, only the functions associated with the role of police officer in the application are available and can therefore be activated via the man-machine interface (same for the “firefighter connection”). For example, the Java instruction bCMS.state_fire_truck_number (2); of the current test program should only be accessible at the “fire brigade connection”. the code is completed , i need interfaces and some javafx or html/css/js adaptation
