Replacing Scalars with their primitive counterparts with graphql-codegen

Question

Using graphql-codegen to generate Typescript types and operations works like a charm using the typescript and typescript-operations plugins.

However the typescript plugin emits types that use Scalar types instead of primitive types:

/** All built-in and custom scalars, mapped to their actual values */
export type Scalars = {
  ID: string;
  String: string;
  Boolean: boolean;
  Int: number;
  Float: number;
};

export type Account = {
  __typename?: 'Account';
  created: Scalars['String'];
}

Can graphql-codegen be configured to emit their primitive counterparts instead? Like so:

export type Account = {
  __typename?: 'Account';
  created: string; // instead of Scalars['String']
}

I've written a custom plugin which drills through all the object's properties, matches correct objects and changes the types, but it is a laborious task. Is there a way to achieve this in a cleaner way?
