 If you want to add a collection with a relation to the collection being included, you have to configure the `populate` parameter in `entriesQuery`. See [the docs](https://docs.strapi.io/dev-docs/api/entity-service/populate) on how it works, and [an example](./resources/entries-query/populate.js) in our resources.
