Срок действия токена доступа Zoom Api истекает, и генерация токена обновления не работает

Я пытаюсь интегрировать Zoom с моим приложением CodeIgneter, используя API с методом OAuth. Я создал токен доступа и успешно интегрировал свою учетную запись Zoom в свое приложение. Через 1 час срок действия ключа доступа к учетной записи Zoom истек. В документе Zoom API говорится, что через 1 час токен доступа истечет, и после этого мы можем сгенерировать токен доступа с помощью Refresh Token.

Использованный документ: Документ OAuth: -

Я создаю функцию для создания токена доступа после истечения срока его действия, используя токен обновления.

Мой код:

$clients = new GuzzleHttp\Client(['base_uri' => 'https://zoom.us']);
$arr_tokens = $this->get_access_token();    
$refresh_tokens = $arr_tokens->refresh_token;
$response = $clients->request('POST', '/oauth/token', [
    "headers" => [
        "Authorization" => "Basic Q2xpZW50X0lEOkNsaWVudF9TZWNyZXQ=". base64_encode(CLIENT_ID.':'.CLIENT_SECRET)
    ],
    'form_params' => [
        "grant_type" => "refresh_token",
        "refresh_token" => $refresh_tokens
    ],
]);

Здесь $ refresh_tokens - это мой токен обновления. CLIENT_ID и CLIENT_SECRET - мой идентификатор клиента и секретный ключ клиента. Я пробую этот код и распечатываю ответ. Но реакция не такая, как я ожидал. Нет токена доступа или токена обновления.
