Xdg-desktop-portal-gnome provides a GNOME implementation for the desktop-agnostic xdg-desktop-portal service. This allows sandboxed applications to request services from outside the sandbox using GNOME services (session manager, screenshot provider, Shell) or GNOME-style user interfaces.

Non-GNOME GTK-based desktop environments should normally use xdg-desktop-portal-gtk or their own portal implementation instead of this one.
