Can't start gnome-software to show a particular snap package

[Stuart Langridge]

I'd like to be able to launch gnome-software showing the details page for a particular snap. I can do this for packages from the Ubuntu archive (gnome-software --details-pkg=inkscape works fine, for example), and gnome-software _supports_ snaps: if I search for ohmygiraffe in gnome-software it finds that snap package no problem. But "gnome-software --details-pkg=ohmygiraffe" does not work, and there seems to be no equivalent option for snaps. I can pass --search=ohmygiraffe but that shows search results with one matching result, not the actual install screen for the snap.
