Selenium Webdriver how to use a proxy like ip:port:log:pass?

I tried to work with a public proxy, but I need uptime 24/7 and high speed. I bought a proxy with a logpass, but I do not know how to cram them. If the code just inserts them in the ip:port location, then when you go to 2ip.ru the screen shows me that the IP is not a proxy, but mine. How to fix it? Code below

( часть выше вставлять не решил, ибо там много мусора )
PROXY = "ip:port:log:pass"

webdriver.DesiredCapabilities.CHROME['proxy']={
    "httpProxy":PROXY,
    "ftpProxy":PROXY,
    "sslProxy":PROXY,
    "noProxy":None,
    "proxyType":"MANUAL",
    "autodetect":False
}

driver_options = Options()
driver_options.add_argument('--headless')
driver_options.add_argument('--disable-gpu')
driver = webdriver.Chrome(r'.\chromedriver', options=driver_options, service_args=["--verbose", "--log-path=D:\\qc1.log"])
driver.get('http://2ip.ru')
time.sleep(5)
driver.save_screenshot("screenshot.png")
