Event Listener for Web Notification

Question

Is there a way to set an event listener for a desktop notification?

document.addEventListener(\"desktop notification\", function(){
    // do something
});

See https://github.com/jiahaog/nativefier project for working sample. Notice snippet (source from https://github.com/jiahaog/nativefier/blob/development/app/src/static/preload.js):

function setNotificationCallback(callback) {

    const OldNotify = window.Notification;
    const newNotify = (title, opt) => {
        callback(title, opt);
        return new OldNotify(title, opt);
    };
    newNotify.requestPermission = OldNotify.requestPermission.bind(OldNotify);
    Object.defineProperty(newNotify, 'permission', {
        get: () => {
            return OldNotify.permission;
        }
    });

    window.Notification = newNotify;
}

So, you replace window's Notification object with own object that act as a proxy with added behaviour (calling callback on creating new Notification).

Hope this helps
