How to convert cookies from selenium to work with requests?

Question

Python

I want to log in to the site using cookies.
I am using requests. I take cookies from selenium.
How do I convert the cookies that I took from selenium to a format that requests understands.
Or how to get cookies without selenium?
Initially, it is not possible to log in to the site through requests.

Example, Selenium Grid 4, Node-chrome (in containers)

import os, json, requests
from selenium import webdriver
from selenium.common import exceptions
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as ec
from webdriver_manager.chrome import ChromeDriverManager

if __name__ == '__main__':
  options = webdriver.ChromeOptions()
  options.add_argument('user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.81 Safari/537.36')
  options.add_argument('--headless')
  options.add_argument('--user-data-dir=/app/google-chrome')
  
  # В моем случае, это Selenium Grid 4
  driver = webdriver.Remote(command_executor=grid_url, options=options, desired_capabilities={})
  driver.get("https://domain.com/some-page-with-cookies")
  
  # Делаем авторизацию, если нужна
  # ...
  
  # Забираем куки и удаляем сессию
  driver_cookies = driver.get_cookies()
  driver.close()
  driver.quit()
  cookies = {}
  for cookie in driver_cookies:
    cookies[ cookie['name'] ] = cookie['value']
  r = requests.get('https://domain.com/target-url', cookies=cookies)
