In GraphQL how to query entries where related entry has a specific value

Question

Lets have this query:

query test {
  entries(section: "vacancies") {
    title
    ... on vacancies_vacancies_Entry {
      description
      organisation {
        title
        ... on organisations_organisations_Entry {
          organisationType
        }
      }
    }
  }
}

Now how would I go about only displaying vacancies from an organisation that has a specific organisationType . I've had a quick read through graphQl docs and couldn't find anything that could help.

I guess I can first query organisations, get their IDs and then pass it to relatedTo parameter to another query, but that's 2 API requests each time I want to make a query. Is it possible to somehow use one graphQL query as a parameter in another graphQl query? Are there any better solutions to this?

I know this question is 1.5+ years old but I landed here looking for something similar and think I found the answer: relatedToEntries. In the docs: https://craftcms.com/docs/3.x/graphql.html#relations

Something like this (replacing 'attributeHandle' and "valueYouWant"):

query test {
  entries(section: "vacancies", relatedToEntries({attributeHandle: "valueYouWant") {
    title
    ... on vacancies_vacancies_Entry {
      description
      organisation {
        title
        ... on organisations_organisations_Entry {
          organisationType
        }
      }
    }
  }
}

Works for me. Hope that helps get someone on the right path!
