libnotify should be quiet
libnotify prints:
Running in confined mode, using Portal notifications. Some features and hints won't be supported
whether or not the features and hints that get set are used.
Given that it already warns about:
libnotify-Message: 15:02:43.424: Category is not available when using Portal Notifications
libnotify-Message: 15:02:43.425: Category is not available when using Portal Notifications
libnotify-Message: 15:02:43.454: Category is not available when using Portal Notifications
It would be great if the library could be made quiet.
