I'm trying to add localization support for a [card](https://nova.laravel.com/docs/1.0/customization/cards.html) built for the Laravel Nova dashboard.

I already created a folder in `/resources/lang` containing the JSON language files in a format like `en.json`. The files get published (copied) with the publish command but the `loadJsonTranslationsFrom()` does not seem to do anything:

```
class CardServiceProvider extends ServiceProvider
{
  public function boot()
  {
    $this->publishes(
      [__DIR__ . '/../resources/lang' => resource_path('lang/vendor/my-custom-card')],
      'my-custom-card-lang'
    );

    $this->loadJsonTranslationsFrom(resource_path('lang/vendor/my-custom-card'));
  }
}

```

This is how the markup in `Card.vue` looks like:

```
{{__('Title')}}

```

How can I test if the JSON files are loaded correctly? What am I missing?

The question is how do I support localization for cards in Laravel Nova?
