Push notification for webapplication

Question

I have a notification screen in my application (Web -React & mobile separate - React-Native frontend / backend nodejs) which lists the current tickets (tickets as notifications) created in the application. I am using push notification to update mobile app notifications. But for web notification list when a new ticket notification is received, I want the web page notifications screen to be updated/refreshed (like in gmail). I don't want to keep doing refresh at pre-determined frequency, is there any other alternative similar to push notification in mobile app. I saw web-push but could not understand it conceptually if it would server the purpose.

Thanks
