cant pass recaptchav2 with callback on GMX.com. python, selenium.

[slamalon]

I am using the callback function but at the end under captcha it says 'Character sequences do not match' on gmx.com

here is my python code, using selenium.

code:

try:
            site_key = "6Lc7GmIUAAAAAKDjVWk0q9Y5HhN5bNr1ctLZDmnw"

            with open(r'api_key.txt', "r") as f:
                api_key = f.read()

                form = {"method": "userrecaptcha",
                        "googlekey": site_key,
                        "key": api_key,
                        "pageurl": driver.current_url,
                        "json": 1,
                        "invisible": 1,
                        "useragent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:84.0) Gecko/20100101 Firefox/84.0"
                        }
            print('this is a form')

            print(form)
            response = requests.post(
                'http://2captcha.com/in.php', data=form)
            request_id = response.json()['request']

            url = f"http://2captcha.com/res.php?key={api_key}&action=get&id={request_id}&json=1"

            status = 0
            while not status:
                res = requests.get(url)
                if res.json()['status'] == 0:
                    time.sleep(5)
                else:
                    requ = res.json()['request']
                    try:
                        time.sleep(5)
                        driver.execute_script(
                            f'document.getElementById("g-recaptcha-response").innerHTML="{requ}";')
                        driver.execute_script(
                            f'___grecaptcha_cfg.clients[0].V.V.callback("requ")')
                        time.sleep(5)

                        print('inner html thing worked...?')
                    except JavascriptException:
                        fail == True
                        driver.quit()
         

                        print('utter failure')

                    try:

                        time.sleep(5)

                        status = 1
                        time.sleep(2)


                        driver.find_element_by_id(
                            "g-recaptcha-response").submit()
                        print('capthac sucessfull...?')
                    except JavascriptException:
                        print("JS FAIL!!")

I have tried to apply what has been discussed on this forum, but nothing seems to work.
