How to make post request to an API and retrieve the response

I'm trying to make a post request in my Command file to an API, which should accept a single key-value pair as a request body and return some statistics in the response body. I'm a beginner in laravel and back-end in general so I'm struggling a little bit with it. When I try to test it on Postman, It works and the body gives me this :

{
    "id": 29,
    "country": "Georgia",
    "code": "GE",
    "confirmed": 2808,
    "recovered": 4123,
    "critical": 4021,
    "deaths": 1730,
    "created_at": "2022-02-13T18:17:01.000000Z",
    "updated_at": "2022-09-08T00:00:03.000000Z"
}

But, when I try to do the exact same thing from my controller, I get the status 200 but I'm not able to see the same response. Here's my command file :

public function handle()
    {
        $client = new Client();
        $res = $client->request('POST', 'https://something', [
            'form-params' => [
                'code' => 'GE',
            ],
        ]);
        dd($res);
    }

When I run this command in the terminal, I get this response :

  }

If I try to dump the body with dd($res->getBody()), I get this response in terminal :

-stream: stream resource {@622
    wrapper_type: "PHP"

    mode: "w+b"

    options: []
  }
  -size: null
  -seekable: true
  -readable: true
  -writable: true
  -uri: "php://temp"
  -customMetadata: []

What am I doing wrong? Any help would be appreciated, thank you!
