To distinguish our versions of Okular from the KDE-provided Windows builds of Okular the application name (i.e. https://doc.qt.io/qt-6/qcoreapplication.html#applicationName-prop) should have one of the following suffixes:
- GnuPG VS-Desktop: -vsd
- GnuPG Desktop: -gpd
- Gpg4Win: -g4w
For Kleopatra this was implemented for T7528: Make it possible to run Kleopatra VSD and Kleopatra GPD in parallel.
