How to pass parameter in Laravel model relation

Question

I made a category tree and I need to pass one parameter to relation, I can't pass them.

public function Child()
{
    return $this->hasMany(Category::class, 'parent_id', 'id');
}

but I want to use variable to pass in relation look like this.

public function Child()
{
    return $this->hasMany(Category::class, 'parent_id', 'id')->where(['owner_id' => $this->ownerId]);
}

then I try to use variable and receive nothing, but if I use hardcoded value then works well. Please help

$models = App\{YourMainModel}::with(['Child' => function ($query) use ($this) {
    $query->where(['owner_id' => $this->ownerId]);
}])->get();
