Как сделать ответ в виде text при запросе с помощью grequests

Код:

def get_free_proxies():
    url = "https://free-proxy-list.net/"
    # получаем ответ HTTP и создаем объект soup
    soup = BeautifulSoup(requests.get(url).content, "lxml")
    proxies = []
    for row in soup.find("table", class_='table').find_all("tr"):
        tds = row.find_all("td")
        try:
            ip = tds[0].text.strip()
            port = tds[1].text.strip()
            host = f"{ip}:{port}"
            proxies.append(host)
        except IndexError:
            continue
    return proxies
free_proxies = get_free_proxies()


sites = []
for page in range(1,287):
    sites.append(f'https://catalog.aquamarine.kz/catalog/products.ashx?rnd=536811965&q=&spec=&mip=317&map=7777%20777&mippg=161&mappg=5466%20222&miw=0.14&maw=137.74&miq=1&maq=241&miprcs=999999.999&maprcs=0&page={page}&sort=art-down&view=2&spc=1,&brid=7')


response = (grequests.post(url, cookies=cookies, data=data, headers=headers, proxies = free_proxies) for url in sites)

a = grequests.map(response)
for i in a:
    print(i.text)

print(f'Время выполнения: {time.time() - start_time} секунд')

Мне нужно получить ответ в виде text. И да я понимаю что grequests.map вернёт просто статус, но я не знаю как тогда делать.
