FileDialog not working anymore

[Creaperdown]

Hey, I am using FolderDialog and FileDialog from Qt.labs.platform, but calling .open() on them, does not open them anymore. It used to work in Qt5, but doesn't with Qt6.

This is how I declare them:

FileDialog {
        id: importFilesDialog
        acceptLabel: "Import"
        fileMode: FileDialog.FileMode.OpenFiles
        folder: StandardPaths.writableLocation(StandardPaths.DocumentsLocation)
}

Does someone have an idea why this doesn't work.
(I am on a KDE distro if this plays a role.)

I have fixed it by linking against the widgets module and changing my QGuiApplication to QApplication

@Creaperdown
Your code worked for me, I am using Mint Xfce.
However, I had to change FileDialog.FileMode.OpenFiles to FileDialog.OpenFiles, because I got a warning.
