E.g:

type Mutation {
    article: ArticleMutations
  }

  type ArticleMutations {
    like: Boolean
    unlike: Boolean
  }

instead of

type Mutation {
   like: Boolean
   unlike: Boolean
}

I've tried having a

fun

returning an object with a method (obviously didn't work),

fun

returning an object implementing

com.expediagroup.graphql.server.operations.Mutation

,

val

returning an object.

Nvm, i read the schema wrong
