How to count order count based on the category?

Question

I have Five tables. They are: category ,Product , product_categories, Order and order products

Category Table

id	Category Title
1	Category One
2	Category Two

Product Table

id	product Title
1	product One
2	product Two

Product Categories Table

id	product_id	category_id
1	1	2
2	2	1

Order Table

id	Order Title
1	Order One
2	Order Two

Order Products table

id	product_id	order_id
1	1	2
2	2	1

So now, I want Category order count through product's product_categories table and Order's order_products table.

It would be very easy if product table have category_id and order table have product_id so that we can easily fetch order count through hasManyThrough relationship.

This is my code that i have tried but it only counts product item.

 $orders['topCategories'] = ProductCategory::with('childs.childs')->withCount(['products'=>function ($query) {
           
                $query->whereHas('orders', function ($query){
                    $query->where('status', true);
                });
        }]);
