I am new to App development and working on an app to tag the Product, then show the tagged products as related products on the product page.
Tagging part seems easy.
But I can not find any docs regarding how to show tagged products in storefront.
I found this blog: https://www.shopify.com/partners/blog/online-store-app-extensions
But it does not too many details. Please point to me where I can learn related topics.
Thanks a lot.
