Get specific columns based on relational tables

I have 3 tables, that are related with each other, and in my index page i wish to retrive all the products data, but in my case when i retrieve all the products is giving me with all the languages. I wish to retrieve all the products of a specific language based on language_id, but cant figure out what to change in my model, since the method ("translatedProducts") that i have in my model only works with single products calling.

DB:

Languages:
- id;
- name;

Products:
- id;
- online;
- price;

Products_Translations:
- id;
- product_id;
- name;
- description;
- language_id;

Model Product method:

public function translatedProducts(){
        return $this->hasMany(ProductTranslation::class);
    }

My current controller calling all products:

$products = Product::all();
