title: Magento 2 - GraphQL custom resolver that returns a list of products
body: <p>I'm searching for a way to build a custom resolver that returns a list of products. I've tried reading the magento code in vendor but I'm not able to reproduce it on my code.</p>
  <p>We already have working resolvers that returns simple types like strings ora arrays.</p>
  <p>If you can post a snippet or some website with an example it would be great</p>
  <p>Magento version 2.3.4</p>
  <p>Thanks</p>
