Icon needed: Privacy screen (guard) activation / deactivation for OSD
Some recent Lenovo models have a builtin privacy screen (see it in action) which can be turned on/off in software, there's some work ongoing that @jwrdegoede is leading to expose this in a way that GNOME can control it and show OSD notifications when it gets enabled/disabled.
So, we'd need two simple icons for such purpose, indicating the on/off state of this feature.
