Unable to set header on graphQL for Retrieving Storefront API translations

We can query the supported resources using the Accept-Language HTTP header, to return translated content to the Storefront API.

Reference:
https://shopify.dev/api/examples/i18n-app-translations#retrieving-storefront-api-translations

Issue:
I was unable to set the header. My attempt was the following:

      $opt = $options->getGuzzleOptions();
      $opt = array_merge_multi($opt, ['headers' => ['Accept-Language' => 'fr']]);
      $options->setGuzzleOptions($opt);

I can see the header is put into _conditional but it does not seem to be passed further.

the output is also not showing the header:
