PWA Push Notifications are sent in Mobile instantly even when instantly read in Desktop

Is your feature request related to a problem? Please describe.
Currently, when having already read the Web Notification in Desktop, the Mobile receives a PWA Push notification.
The same notification seems redundant and thus requires attention from user twice. This can be annoying especially when already having read the notification from Desktop.

Describe the solution you'd like
The redundant notification on Mobile can be avoided by deferring sending Mobile notification by 1 minute or more for some types of notifications, like an activity publication (in contrary to Chat mention by example). This way, when deferring the sending process, if the Notification has been read in the meanwhile, no notification will be sent to the user.

Another solution could be, when the user is connected on Desktop, avoid sending the notification on Mobile or at least defer sending Mobile notification by few minutes.

Another process may be added as well to clean periodically the Mobile notifications when it has been marked as read using any other device, this way, we avoid the Mobile OS notification This site has been updated...
