How do adjust the position of MenuItem when Menu creates MenuItems using Instantiator?

[mirro]

Menu {
    id: recentFilesMenu

    Instantiator {
        model: recentFilesModel
        MenuItem {
            text: model.fileName
        }
        onObjectAdded: recentFilesMenu.insertItem(index, object)
        onObjectRemoved: recentFilesMenu.removeItem(object)
    }

    MenuSeparator {
        visible: recentFilesModel.count > 0
    }

    MenuItem {
        text: "Clear menu"
        enabled: recentFilesModel.count > 0
        onTriggered: recentFilesModel.clear()
    }
}
