Hey @Sradha,
You can use the below code:-
System.setProperty("webdriver.chrome.driver","C:\\Users\\Nabarupa_Das\\Downloads\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("--incognito");
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver=new ChromeDriver(capabilities);
Hope this helps.
