VS Code

can anyone tell me where the protected guarded id goes and how to format it into the code. The code isn't accepting it

<?php

namespace App\Models;

use App\Traits\Sortable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Factories\HasFactory;

class Vacancy extends Model
protected $guarded = ['id'];

{
/** @use HasFactory<\Database\Factories\VacancyFactory> */
use HasFactory, Sortable;

public function applications():  HasMany {
    return $this->HasMany(Application::class);
  }

}   


//add applications has many relationship

public function casts(): array
{
    return [
        'application_open' => 'date',
        'application_close' => 'date',
    ];
}

public function scopeSearch(Builder $query, $search) {

    return $query->where('title', 'like', "%{$search}%");
}
