ایجاد eloquent sluggable در لاراول

من قبلا برای پشتیانی از فارسی برای ایجاد مسیر در لارول از خط زیر اسفاده کردم.

اما من امروز این پکیج رو نصب کردم. و بعد از publish کردن هنوز فایل sluggable.php در پوشه config پیدا نکردم که بخوام از متد methods خط زیر را کپی کنم.

  php artisan vendor:publish --provider="Cviebrock\EloquentSluggable\ServiceProvider"

فایل sluggable.php

    $_transliteration = ["/ö|œ/" => "e",
