How to implement a relationship through a table in Laravel?

Question

Laravel

I'm trying to get caracteristics with relations to product_mod_characteristics.

Now for this I do this:

class ProductMod {
    public function characteristics(): HasMany
    {
        return $this->hasMany(ProductModCharacteristic::class);
    }

    public function getCharacteristics(): array
    {
        $characteristicsId = $this->characteristics()
            ->select('characteristic_id')
            ->distinct()
            ->pluck('characteristic_id')
            ->toArray();
/**
затем запрашиваю caracteristics со связью к product_mod_characteristics
*/
}

Is there a way built into the engine?
As far as I understand, the method "One to one through" and "One to many through" will not work here.
