Gmail and G-Suite (professoinal Gmail) allow useful notifications. But those notifications only popup while a Gmail tab is open (such as in the background or not visible). So I like to open gmail while I am waiting for an email, I will get the notifications, can read the email, then close that tab and notifications are no longer arriving. One of the very few use cases for notifications that I appreciate. I have the same setup for Slack & Discord online versions.
