Remove the union for types that implements node

[calvo-jp]

Hello. I am trying to migrate a setup which generates all the types exactly like what the server has into something which is based on just the documents nodes that we write.

This is currently my .graphqlrc.js config

/** @type {import('graphql-config').IGraphQLConfig} */
const graphqlConfig = {
  schema: process.env.NEXT_PUBLIC_API_URL,
  documents: './src/graphql/**/*.ts',
  extensions: {
    codegen: {
      hooks: {
        afterAllFileWrite: ['prettier --write'],
      },
      generates: {
        './src/__generated__/graphql.ts': {
          plugins: [
            'typescript',
            'typescript-operations',
            {
              add: {
                content: '/* eslint-disable */',
              },
            },
          ],
          config: {
            disableDescriptions: true,
          },
        },
        './src/__generated__/introspection-result.ts': {
          plugins: ['fragment-matcher'],
          config: {
            useExplicitTyping: true,
          },
        },
      },
    },
  },
}

this outputs something like this

export type QueryName = {
  __typename?: 'Query'
  resource?:
    | { __typename?: 'A' }
    | { __typename?: 'B' }
    | {
        __typename?: 'C'
        id: string
        prop1: any
        prop2: any
}

but, that is not exactly what I want to have. Is it possible to generate something like below.

export type QueryName = {
  __typename?: 'Query'
  resource?: {
        __typename?: 'C'
        id: string
        prop1: any
        prop2: any
}

this way it does not affect the current codes that we have and only the types need to be updated then. I've tried playing with the configs on the docs but could not produce something like this. Thanks in advance
