reactjs – GraphQL and React – Set default enum values in graphQL schema so the enum’s are generated with said values

I’m using React Typescript front end with a GraphQL backend. Currently I have a .schema.ts file that contains:

import gql from 'graphql-tag';

export default gql`
   enum MyEnum {
      First
      Second
      Third
   }
`

I then have a .resolver.ts file that contains:

export default {
   Mutation: {
      //mutations here
   },
   MyEnum: {
      First: 10,
      Second: 12,
      Third: 15
   }
}

However when I run generate in the api folder, the generated GraphQL enum in generated/graphql.ts is:

export enum MyEnum {
      First = "First",
      Second = "Second",
      Third = "Third"
   }

Is there something that I am missing to get the enum to generate with the specified default values?
