There's information about adding push notification support to a web app at https://developers.google.com/web/fundamentals/codelabs/push-notifications/

One approach, if you're not already tied to a given push messaging provider, is to use Firebase Cloud Messaging, which ships with a library to simplify implementing your service worker's push handler.

In general, if you're curious about when various bits of code inside your service worker actually execute, this answer might be helpful. You do need to implement push notifications in a service worker to get the behavior you describe.
