Filter by many-to-many relationship pivot column

If you have a many-to-many relationship, and you add an extra column to the pivot table, here's how you can order by it when querying the list.

1class Tournament extends Model
2{
3    public function countries()
4    {
5        return $this->belongsToMany(Country::class)->withPivot(['position']);
6    }
7}

1class TournamentsController extends Controller
2 
3public function whatever_method() {
4    $tournaments = Tournament::with(['countries' => function($query) {
5            $query->orderBy('position');
6        }])->latest()->get();
7}
