list products eloquent when receiving the category id

Im my system:

products id name ...

categories id name ...

subcategories id name ...

products_subcategories id product_id category_id subcategory_id order

this is not working:

$products= \App\Product::subcategories()->wherePivot('category_id',$category->id) ->wherePivot('subcategory_id',$subcategory->id);

how do I list products when I receive an id category and an id subcategory? with pagination?
