Notification manager - no right mouse click


I am - like for always - using the notification manager and it never bothered or occurred to me that the mouse right click is not handed to the icon / app behind but it shows a context menu for the notification manager.

Now I found an Application - nextcloud-desktop which is quite annoying if you can't get to it with the right mouse button.


Was it always this way? Did something change and I missed it? or is it even better - configurable?

Any help appreciated.
