Add a confirm exit message (like uiconfirm) for a WebApp

I am migrating one of my Standalone apps to a Matlab Webapp and indeed there are a lot of things to be removed, changed and modified as they do not work for a Web-application (listed here). I would like to however include one feature that will demand confirmation from the user when he tries to close the window.

Usually, for a standalone app, this is what I do (my CloseRequest function):

 function figure1CloseRequest(app, event)
    anss = uiconfirm(app.figure1, 'Do you wish to quit?', 'Confirm Exit', 'Options',{'Yes','No','Cancel'}, ...
        'DefaultOption',3,'CancelOption',3, 'Icon', 'question');
            
     switch anss
        case 'Yes'
            closereq();
         otherwise
            return;
     end       
 end
 

However, this feature does not work in a Web-app. Is there a workaround to add something like this in a Web-app?

I see that 'uiconfirm' is supported for web apps. From the link you shared,

• However, uialert, uiconfirm, and uiprogressdlg are supported.

Here's a tutorial on how to use uiconfirm and deploy it as a web app from MATLAB.

Yes. uiconfirm works. But I would like to add it to confirm when we close the tab.

The code that I provided above, it works when I launch it on App-designer. But when it is launched on a browser, the uiconfirm to close the window does not work.
