Description kelson 2023-07-26 16:33:43 UTC 
On a system without a full KDE environment, if I install just Plasma Discover (whether through dnf or through Gnome Software), I get a partially-working Discover app. It loads, and it shows categories and lists of apps, but it can't load the info page for an application. I was able to get it to work by also installing the kf5-purpose package through dnf.

Reproducible: Always

Steps to Reproduce:
1. Take a Fedora 38 system without KDE (I found this on Gnome)
2. Install the plasma-discover RPM (dnf or GNOME Software)
3. Run Discover
4. Click on an application entry for more information.
Actual Results:  
Nothing happens in the GUI.

If you run it from the command-line, the console outputs

file:///usr/lib64/qt5/qml/org/kde/kirigami.2/PageRow.qml:914: Error: Error while loading page: qrc:/qml/ApplicationPage.qml:15 module “org.kde.purpose” is not installed

Expected Results:  
Discover should switch to a page showing additional detail, description, reviews, etc. for the application.

Installing kf5-purpose via dnf solves the problem. So making it a dependency for the plasma-discover RPM should fix it.
