How can i fetch Collection with its product details in one query. What i've done is fetch all collection first then from in it i've fetched the id and one by one step wise i include the id in another query then i got the product details.

But i want all in one query. Check my code

step1) made query for getting collection
step2) call it
step3) made query for getting product details from collection response
step) call it

 Storefront.QueryRootQuery query = Storefront.query(rootQuery -> rootQuery
 .shop(shopQuery -> shopQuery
 .collections(arg -> arg.first(10), collectionConnectionQuery -> collectionConnectionQuery
 .edges(collectionEdgeQuery -> collectionEdgeQuery
 .node(collectionQuery -> collectionQuery
 .title()
 .products(arg -> arg.first(10), productConnectionQuery -> productConnectionQuery
 .edges(productEdgeQuery -> productEdgeQuery
 .node(productQuery -> productQuery
 .title()
 .productType()
 .description()
 )
 )
 )
 )
 )
 )
 )
 );


 @Override
 public void onResponse(@NonNull GraphResponse<Storefront.QueryRoot> response) 

 List<Storefront.Collection> collections = new ArrayList<>();

 for (Storefront.CollectionEdge collectionEdge : response.data().getShop().getCollections().getEdges())
 

 collections.add(collectionEdge.getNode());


 for (Storefront.ProductEdge productEdge : collectionEdge.getNode().getProducts().getEdges())
 
 products.add(productEdge.getNode());
 


 for (int i = 0; i < products.size(); i++)
 
 Log.i("PRODUCTS", String.valueOf(products.get(i).getId().toString()));
 

 

 getActivity().runOnUiThread(new Runnable()
 

 @Override
 public void run()
 

 product_recyclreview.setVisibility(View.VISIBLE);
 shimmer.setVisibility(View.GONE);

 productAdapter = new ProductAdapter(getActivity(), products);
 product_recyclreview.setAdapter(productAdapter);

 mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener()
 

 @Override
 public void onRefresh()
 

 Refresh();
 mSwipeRefreshLayout.setRefreshing(false);

 

 );

 

 );
