I think com.kms.katalon.core.webui.driver.DriverFactory#changeWebDriver(WebDriver) method is an important one. It is refered in some official documents :
On the other hand, the official API doc does not show the changeWebDriver method:
this page does not show changeWebDriver method.
This inconsitency worries me. Is the changeWebDriver method an Katalon-internal one which is designed for the Katalon Team internal use only?
