Eloquent in laravel route

Question

i am trying to return data of the Staff , Staff_shops and Shop class in a route in order to get what shop that specific staff working on. I am trying to call by using eloquent

below is from Staff class

 public function Staff_shop()
    {
        return $this->belongsTo(
            Staff_shop::class, 'user_id');
    }

below is from Shop class

public function Staff_shop()
    {
        return $this->belongsToMany(
            Staff_shop::class, 'shop_id');
    }

and below is from the Staff_shop class . Staff_shop is the bridge between Staff and Shop model

  public function shop()
    {
        return $this->hasOne(Shop::class);
    }

    public function staff()
    {
        return $this->hasOne(Staff::class);
    }

how i can write the correct way in this route below to dd()

Route::get('/testStaffShop', function () {



    dd( ... );

});
