QUESTION: find() and filtering by relation

[MathiasOdlund]

Hey,
I tried to ask my question over at the Nuxt Discord server without much luck.

I have two collection types that has relations with eachother:

• Products
  • Name
  • slug
• Subitems
  • name
  • description
    Each Product can have any number of SubItems. Just like SubItems can belong to any number of Products.
    While querying for SubItems, I was wondering how I could search for SubItems that belongs to a certain product using the product slug to identify the product.

const product = await findOne("products", route.params.id);
const subItems = await find("subItems", { filter: someCodeThatTellsMeHowToFindSubItemsUsingTheProductSlug. });
