How to refresh DirectoryTree to see new files/folders?

[toiletsandpaper]

This does't work at all:

def on_button_pressed(self, event: Button.Pressed):
    if event.button.id == 'button-refresh-tree':
        logger.info('Refresh Tree button pressed')
        tree: DirectoryTree = self.query_one('#tree-view', DirectoryTree)
        tree.refresh()

And this is working, but seems very inefficient:

def on_button_pressed(self, event: Button.Pressed):
    if event.button.id == 'button-refresh-tree':
        logger.info('Refresh Tree button pressed')
        app.pop_screen()
        app.uninstall_screen('file-picker')
        app.install_screen(FilePickerScreen(), name='file-picker')
        app.push_screen('file-picker')

As far as I'm aware there isn't an option to get DirectoryTree to reload, at this time. That does feel like something that could do with adding.
