DBUS calls to Gnome Shell don't work in Tails 6

[BenWestgate]

Describe the bug A clear and concise description of what the bug is. To Reproduce Steps to reproduce the behavior:

1. Notice the notifications are not being cleared by the dbus commands anymore.

Expected behavior I expect Bails to not put notifications on the lock screen that reveal what applications are running underneath. As well as to not waste memory storing hundreds of these.

Screenshots

Additional context One option is to minimize the usage of notifications.

Another is to see if the notifications can be set to not show on the lock screen.

Another may be Do Not Disturb mode.

Dialogs could be launched to provide the same information.
