 To use this test, use the build script in flatpak-build/ to produce a flatpak of portal-test, then install it with
 
     flatpak remote-add --user --no-gpg-verify portal-test-kde file:///path/to/repo
-    flatpak install --user portal-test-kde org.kde.PortalTest
+    flatpak install --user portal-test-kde org.kde.portal-test-kde
 
 and run it with
 
-    flatpak run org.kde.PortalTest
+    flatpak run org.kde.portal-test-kde
 
 The test expects the xdg-desktop-portal service (and a backend, such as xdg-desktop-portal-kde) to be available on the session bus.
