ChromeWebdriver sees website differently than I do (Python)

I'm trying to make a script that logs into my online grade book to look for any changes (new grades, etc). This is my code so far.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager
import time

def main():
    options = Options()
    # options.add_argument("--headless")
    driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=options)
    driver.maximize_window()
    # goes to the desired website
    driver.get('https://portal.librus.pl/rodzina')
    # searches for and clicks a button that drops down a menu in which link for login form is visible
    button = driver.find_element(By.CLASS_NAME, 'btn.btn-third.btn-synergia-top.btn-navbar.dropdown-toggle')
    button.click()
    # searches and clicks login link
    agree = driver.find_element(By.CLASS_NAME, 'zmdi.zmdi-account.dropdown-item__icon')
    agree.click()
    time.sleep(10)
    driver.quit()


if __name__ == '__main__':
    main()

And there is a problem, I cannot seem to find a way to make webdriver see what I see. What I mean is that I see the webpage like this and webdriver sees the same webpage like this also the source code is different. I've tried using undetected ChromeDriver with no success. This is my code using UC.

import undetected_chromedriver as uc
import time
from selenium.webdriver.common.by import By


def main():
    driver = uc.Chrome()
    driver.maximize_window()
    # goes to the desired website
    driver.get('https://portal.librus.pl/rodzina/home')
    # searches for and clicks a button that drops down a menu in which link for login form is visible
    button = driver.find_element(By.CLASS_NAME, 'btn.btn-third.btn-synergia-top.btn-navbar.dropdown-toggle')
    button.click()
    # searches and clicks login link
    agree = driver.find_element(By.CLASS_NAME, 'zmdi.zmdi-account.dropdown-item__icon')
    agree.click()
    time.sleep(5)
    driver.execute_script("window.print();")


if __name__ == '__main__':
    main()

Has anyone had a similar problem and managed to solve it?
