Laravel Voyager Admin Panel Can Not See Accessor

I have Product and Category model. Category entities takes parent_id which is linked to Category itself. I want to see full category tree on the admin panel. I'm trying to define an accessor named as "full_path" to the Category model. So I will use this in the Product model with category field. Here is code:

<?php

namespace App;
use Illuminate\Database\Eloquent\Model;
use TCG\Voyager\Traits\Translatable;

class Category extends Model
{
use Translatable;
protected $translatable = ['name', 'description'];
public $additional_attributes = ['full_path'];

public function withTranslation() {
return $this->load('translations');
}

public function getFullPathReadAttribute()
{
$path = $this->name;
$parent = $this->parent;

while ($parent) {
$path = $parent->name . ' > ' . $path;
$parent = $parent->parent;
}

return $path;
}
}
