BelongsToManyThrough in Eloquent

I have tables as below :

store 
id
name

category
id
parent_id
name

product
id
name

category_product
product_id
category_id

store_category
store_id
category_id

store_product
store_id
product_id

Models :

Store.php

public function category()
    {
        return $this->belongsToMany(Category::class,'store_category');
    }

 public function product()
        {
            return $this->belongsToMany(Proeuct::class,'store_product');
        }



public function storeCategoryProducts()
    {
        return $this->category()->with('products');
    }

Category.php

 public function parent()
    {
        return $this->belongsTo(Category::class, 'parent_id');
    }

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

 public function products()
    {
        return $this->belongsToMany(Product::class,'category_product','category_id','product_id');
    }

 public function store()
    {
        return $this->belongsToMany(Store::class,'store_category','category_id','store_id');
    }

Product.php

 public function Category()
    {
        return $this->belongsToMany(Category::class, 'category_product', 'product_id',
            'category_id');
    }

 public function Store()
    {
        return $this->belongsToMany(Store::class,'store_product','product_id','store_id');
    }

Now, i want to fetch all data by store id as below format :

store
 relation => Parent_category
                    relation=> child_category
                                  relation=>product

What i have tried :

Store::with('storeCategoryProducts')->where('store_id',$storeId)->first()

I am getting the data as in the format i need but getting products of all stores, but i need the product of the specific store that are related to $storeId Is there any other way to do this with eloquent .

Any suggestion are appreciated.
