Is there a way that we could have some persistent storage for when the last authentication error happened? This would allow showing a /!\ icon in the device list even though we don't have an agent running in the session, just when the settings are open, in GNOME. This would also allow the settings to get this information in the first place, otherwise we'd need to have some side-channel to funnel that information from the "desktop-wide" agent to the settings agent. I've made the upstream bug[1] public now, can you reference it in the commit message? Cheers [1]: https://gitlab.gnome.org/GNOME/gnome-bluetooth/-/issues/91
