Styling with Tailwind in admin area

Thank you!
How do you get editor.scss working properly?
Did you enqueue it somewhere?
How does WP know it has to load this css only in admin?

I found a serious post about how to implement css files for gutenberg editor: Post by @Simeon

So i edited config.json adding this:

"gutenberg": ["./styles/gutenberg.scss"],

and in my setup.php adding this:

add_action('enqueue_block_editor_assets', function () {
     wp_enqueue_style('sage/gutenberg.css', asset_path('styles/gutenberg.css'), false, null);
});

But somehow I have not yet got it working. If i look into the console while i’m editing a gutenberg block, i get an 404 error for this gutenberg.css: MIME-Type conflict
