gnome-software missing an install/upgrade button when opening an .rpm file

Please describe the issue you’re experiencing:

I downloaded a Crossover 22 .rpm file. When I click it, it automatically opens in gnome-software - but there's no button to install/upgrade, only uninstall. I have version 21 installed, but I should be able to upgrade without having to uninstall it first. In any case, not having an "upgrade" button is very confusing.

What Linux distribution are you using, and what kind of package (RPM, deb, flatpak, etc.) are you experiencing the problem with?

Fedora 36, RPM

Please attach a log of the issue, by running the following commands, reproducing the issue, and then attaching gnome-software.log here:

pkill gnome-software
gnome-software --verbose &> gnome-software.log
