Loading assets in wordpress Admin (with ACF fields)

Hi there!
I need to import specific css files in the admin, in the content management with ACF (Not Gutemberg).
Everything is OK with the following action/function:

add_action('after_setup_theme', function () {
    // [...LOOOOOT A CODE....]
     add_editor_style( 'public/editor.b58abb.css' );
}, 20);

But … how to get the name of my file with its extension added during the build with bud?
Acorn seems to have several functions, but none of them seems to return only “editor.b58abb.css”

Thanks a lot for your help!
