The demo is super helpful for implementing the library. It took me a minute to set it up only because it was awkward to copy the VAPID values out.

As far as I can tell, a new web push notification always pops and goes to a new tab with a URL. This library would be better if it implemented the subtleties and considerate practices that:

- Focus an Existing Window or Tab: https://web.dev/articles/push-notifications-common-notification-patterns#focus_an_existing_window
- Suppress Notification if Tab is already Focused: https://web.dev/articles/push-notifications-common-notification-patterns#the_exception_to_the_rule

The component greatly simplifies the solution compared to other alternatives that we evaluated for the need to send push notifications by web application.
