Can I send a browser push notification when PWA is closed?

are you somehow able to send an Browser Push Notification like they’re known from e.g. Youtube? They send them although you aren’t on the website.
If there is an way, please also tell me how to manage the notificatons - until now I only know how to handle the User UI…

Best Regards

I think you have to use a service worker and the notification API for that.
