Proxy with Authentication in Selenium, JAVA

We try to use authenticated proxy in Selenium driving headless Chrome, JAVA.

ChromeOptions inherit from ChromeCapabilities (deprecated). We pass instance of Proxy class into a ChromeOptions instance.

The Selenium Proxy class has no methods of HTTP proxy to set up username & password:

        Proxy proxy = new Proxy();
        proxy.setAutodetect(false);
        proxy.setHttpProxy(proxyStr);
        proxy.setFtpProxy(proxyStr);
        proxy.setSslProxy(proxyStr);  
        chromeOptions.setCapability("proxy", proxy);
    

Any way out?
