Convert GraphQL query to string with typename

I'm using Pact to mock our server side with graphql(Apollo) client. After trying some examples manually I did notice that majority of our current code performs exports like this:

import { gql } from '@apollo/client';

export const GET_USER_DETAILS = gql`
  query GetUserDetails {
    current_user {
      id
      first_name
      last_name
      username
      email
      gender
      birth_date
      home_phone
      mobile_phone
      }
  }
`;

My question is how can I convert this back to string representation to give to withQuery method of Pact ?

Extra complexity is that we are using Apollo cache which means that I need to add __typename to each document which I did using

import { addTypenameToDocument } from '@apollo/client/utilities';
addTypenameToDocument(GET_USER_DETAILS)

I tried addTypenameToDocument(GET_USER_DETAILS).loc.source.body - no __typename present here which is causing Pact to fail mocking due to difference on expectation and actual query.

Use print from the graphql package (which you should probably already have installed).

import { print } from 'graphql';

console.log(print(GET_USER_DETAILS));
