Hi!
Your code is awesome!
but, How can i send websocket message?

I am not able to print all msg in websocket frame

Do not get the Network Websocket message on the remote webdriver. Are there any configurations that we need to set to get the messages on remote webdriver?

Use this code!

**System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir") + File.separator + "drivers" + File.separator + "chromedriver.exe");

LoggingPreferences loggingprefs = new LoggingPreferences();
loggingprefs.enable(LogType.PERFORMANCE, Level.ALL);

ChromeOptions options = new ChromeOptions();
options.setCapability("goog:loggingPrefs", loggingprefs);
options.addArguments("--enable-devtools-experiments", "--force-devtools-available", "--debug-devtools");

ChromeDriver chromeDriver = new ChromeDriver(options);
DevTools devTools = chromeDriver.getDevTools();
devTools.createSession();
devTools.send(Network.enable(Optional.empty(), Optional.empty(), Optional.empty()));`

devTools.addListener(Network.webSocketFrameSent(), webSocketFrameSent -> printData(webSocketFrameSent));
devTools.addListener(Network.webSocketFrameReceived(), webSocketFrameReceived -> printData(webSocketFrameReceived));**
