La-belling the bug accordingly to get attention from respective team for this feature request.

Hi, thanks for your feature request. 

However, I'm struggling to understand what exactly this feature request is for - please can you explain what is meant by 'the display time'? Is this the duration, the time at which the notification should appear, or the time displayed visually on a notification? 

What I meant with the notification display time is that there is no setting to change when a notification should disappear after a specific time.

So in practice the notifications from chrome should disappear after displaying for a while.
The problem is that the notifications never goes away.

Also needs same control on Mac OS. For example, duration of the notification "badge" or banner for mic.com udpdates, when it displays on desktop screen, is only about 2 seconds, then it goes away. There's not enough time to click on it to go to the story.

We have two kinds of notifications:
  - Regular ones, that disappear after a short amount of time.
  - Ones that require interaction, which will remain on screen.

For some kind of notifications that is important, notably calendar appointments, which require more pressing attention than many other kinds of notifications.

We don't currently have a method to allow you to change for how long these will remain on screen. While I'm not opposed to adding a command line flag for this purpose, the benefit will be limited, because we're in the progress of switching to native notification centers where this'll be out of our control.

Notably, on Mac, these notification types respectively map to banners and alerts. If you wish to change one to the other, or have both either stay on screen or dismiss automatically, you can change this in the system's notification settings screen, where you'll find Chrome listed.

Now with native system notifications I want to increase the time when I see them - I do not want to miss anything important.

The following article might be helpful for extending the notification display time on Windows 10:

Based on that and #c8, let's mark this as WontFix.
