Как из объекта GuzzleHttp\Psr7\Response вытащить определенную часть?

После авторизации на сайте через guzzle и запроса cookie, возвращает такой объект

object(GuzzleHttp\Psr7\Response)#33 (6) {

как работать с ним? А точнее как вытащить только ["Set-Cookie"]=> array(1) { [0]=> string(153) "csrftoken=ovUMpXKW0GekKVTdN1ntF1teYYkqtyNE3pws2i7N437sYuZv1nhzKtl1uQ5STnpi; expires=Wed, 23 Nov 2022 13:33:28 GMT; Max-Age=31449600; Path=/; SameSite=Lax" } Помогите пожалуйста. Работаю с guzzle на PHP
