async fn keyring_with_dbus_fallback() -> Result<Keyring, Box<Error>>Expand description
Try oo7::Keyring::new(), which auto-selects portal (Flatpak) or
D-Bus (native). If the portal backend fails – common on Hyprland,
Sway, XFCE, and other non-GNOME/KDE desktops – explicitly attempt
the D-Bus Secret Service as a fallback before returning an error.
