KDE's desktop portal seems to be missing


I can find the package with swupd search in desktop-kde, which I have installed but the portal isn’t.
The xdg-portal checker Door Knocker also doesnt’t find a working implementation on KDE.

I couldn’t manually change it to the Gnome or GTK portal nor build it from source because I can’t find the KFrameworks 6 dev bundle either.

Thanks for any help in advance.
