How to use the @graphback/codegen-client.createClient function in @graphback/codegen-client

export async function initGraphbackClient(
  context: InputModelTypeContext[]
): Promise {
  const fragments: StringDic = {};
  const queries: StringDic = {};
  const mutations: StringDic = {};
  const subscriptions: StringDic = {};

  const client = await createClient(context, { output: "gqlwithfragment" });

  if (client.fragments !== undefined) {
    insertImplInto(client.fragments, fragments);
  }

  if (client.queries !== undefined) {
    insertImplInto(client.queries, queries);
  }

  if (client.mutations !== undefined) {
    insertImplInto(client.mutations, mutations);
  }

  if (client.subscriptions !== undefined) {
    insertImplInto(client.subscriptions, subscriptions);
  }

export async function createClientFiles(cwd: string, inputContext: InputModelTypeContext[], config: GenerateConfig) {
  const generated = await createClient(inputContext, { output: config.generator.client.format });
  await Promise.all([
    createFragments(cwd, generated, config),
    createQueries(cwd, generated, config),
    createMutations(cwd, generated, config),
    createSubscriptions(cwd, generated, config),
  ]);
}

public async createClient(): Promise {
    return createClient(this.inputContext);
  }
}
