VLC directory is hidden in Files.app when empty

When there are no files in VLC's Documents directory, the iOS 11+ Files.app won't show VLC.
We could :

touch a (dot)file on start (dotfiles are not shown in neither Files.app nor iTunes therefore the user should not be able to delete any of them);
move the media into an intermediary directory (which would solve several other issues by the way).
