Using proxy with undetected_webdriver in Python not working

I am trying to use proxies in undetected_webdriver module but it is not working. It worked for me before with selenium using the following method:

webdriver.DesiredCapabilities.CHROME['proxy'] = {
        "httpProxy": self.proxy,
        "ftpProxy": self.proxy,
        "sslProxy": self.proxy,
        "noProxy": None,
        "proxyType": "MANUAL",
        "class": "org.openqa.selenium.Proxy",
        "autodetect": False
    }

when I try this with undetected_webdriver and see the website whatismyip my ip still the same. I went with Proxy class and the issue was still the same.

Is there a way to make it happen with undetected_webdriver?
