How to implement notifications on the site?

Question

Laravel

Laravel already has a built-in function for notifications, but I'm interested in a way to implement real-time notifications.
I googled, but in the end I did not find anything sensible. Who knows the links to some Example-tutorial on the implementation of notifications?
Mail notifications have already been implemented according to the documentation, now I want to know how real-time notifications are done, and how it is processed on the client side in the browser.
Thanks to all!
