@Letraindusoir You can include the following in the goog:ChromeOptions:
"excludeSwitches": ["enable-automation"], "useAutomationExtension": false
My current wording of $sDesiredCapabilities looks like this and it works for me.
$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"unhandledPromptBehavior": "ignore", ' & _
'"goog:chromeOptions": {"w3c": true, "excludeSwitches": ["enable-automation"], "useAutomationExtension": false, ' & _
'"prefs": {"credentials_enable_service": false}, "args": ["start-maximized"] }}}}'
