javascript - How to capture or listen to browser notifications?

I want to listen to ining notifications on the chrome browser for sites like google, facebook, whatsapp etc. I saw that the hack mentioned here which no longer works because webkitNotifications.createNotification is deprecated. Some of these sites use service workers, so I wonder if I can use webAPIs like ServiceWorkerRegistration.getNotifications(), PushManager, ServiceWorkerGlobalScope or even the Notification API? I've been reading around and cannot find anything to do this. I don't mind a hack as well. Can anything be done using selenium? Is it possible at all? If not, I'll not waste more time on it. Cheers!

Note: I'm looking for a solution where I can listen to notifications on other websites, not mine.

What a general purpose? Do you want to collect your notifications in one place? Browser doesn't allow you to mess with a context of other pages from your page. Maybe extension can, but i'm not sure. – Dmitry Manannikov Commented May 18, 2017 at 7:03

I needed exact same thing. I assume you are looking for Chrome extension or App. I had no ways to access or intercept notifications shown through service workers (usually ones shows even after browser close). But the ones using Notications API in page you can simply customize Notications with your version of object as mentioned in: Event Listener for Web Notification

Put this in content script of extension and load before page is loaded in Chrome and listen to every events raised from page.
