It's important to note that not all portals are implemented on all desktop environments. You can see this as a reference table: https://wiki.archlinux.org/title/XDG_Desktop_Portal#List_of_backends_and_interfaces

You also use the portal helper from another DE though.

For example, the Niri Wayland compositor, written in Rust with Smithay, uses xdg-desktop-portal-gnome (which I imagine is written in C).

We don’t have windows, so we had to make do with this interdimensional portal.
