WebUI.maximizeWindow() not working for katalon docker image?

WebUI.maximizeWindow() does not work for katalon docker image,

The command works fine on Katalon desktop, but when I run this on docker image it seems to ignore the command completely.

WebUI.openBrowser(GlobalVariable.url, FailureHandling.STOP_ON_FAILURE) WebUI.maximizeWindow(FailureHandling.STOP_ON_FAILURE)

The window should be maximized after using that command!
