GraphQL mutation with union type

Hi everyone,

Are mutations with union types already supported, like in the example below? (I’m using apollo client)
The dgraph docs show only a query example.

mutation {
  addHome(input: [
    {
      city: "San Francisco"
      members {
        ...on Dog: [
          {
            name: "Cesar"
          }
        ]
        ...on Human: [
          {
            name: "John"
          }
        ]
      }
    ]) {
    home {
      city
      members {
        ...on Dog {
          name
        }
        ...on Human {
          name
        }
      }
    }
  }
}

Thank you!

Not as in the example you posted, but union mutations are supported in the way shown here: https://dgraph.io/docs/master/graphql/mutations/mutations-overview/#union-mutations
