How to set Chrome experimental option same-site-by-default-cookie in python selenium

Question

I suppose this should work:

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option(\'same-site-by-default-cookies

Tested on Chrome : Version 79.0.3945.130 (Official Build) (64-bit)

In Python you can use below code

    chrome_options = webdriver.ChromeOptions()
    experimentalFlags = ['same-site-by-default-cookies@1','cookies-without-same-site-must-be-secure@1']
    chromeLocalStatePrefs = { 'browser.enabled_labs_experiments' : experimentalFlags}
    chrome_options.add_experimental_option('localState',chromeLocalStatePrefs)
    driver = webdriver.Chrome(options=chrome_options)
    driver.get("https://www.bing.com")

Python selenium client will send the capabilities as below
