This does not work for me in Debian Bookworm with XFCE 4.18, nothing
happens if I try to add a file in the compose window, I'm only getting:

$ GTK_USE_PORTAL=1 claws-mail

(claws-mail:389314): GLib-GObject-WARNING **: 22:24:51.065: invalid cast from 'GtkFileChooserNative' to 'GtkWindow'

Translated:
Can't open portal file chooser: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface ?org.freedesktop.portal.FileChooser? of the object in the path /org/freedesktop/portal/desktop
 
Also installing xdg-desktop-portal-gtk and the suggested package
xdg-desktop-portal-gnome or xdg-desktop-portal-kde does not change
anything. Only xdg-desktop-portal was installed beforehand, maybe
because of some recursive reverse dependency, dunno.

Anyway, everything works fine here without GTK_USE_PORTAL=1 and I don't
bother to debug something which was afair mostly invented because of
some flatpak strangeness ;)

Bye,
