Passing variables between mutations (or queries)

[3goats]

Hi sorry for the direct question, but I can't seem to find an answer to this anywhere. I've already asked the question as an issue in #8094 but thought it better to start a discussion.

I have a GraphQL mutation that creates an item and returns the data that's created. I need to pass some of the created fields into another mutation (or maybe a query). Is this possible? This is almost working but I can't figure out how to get the data between the mutations:

mutation {
    createToken(
        input: { tokenname: "my token", tokendescription: "my valuable token" }
    ) {
        id
        randomdata
    }
  insert__helloworld_article(objects: [{randomdata: $randomdata , author_id: 1}]) {
    returning {
      id
    }
  }
}

So the question is getting "randomdata" from the mutation to insert into the helloworld_article query.
