Verify browser is opened by windows application

I’m testing a windows application (WPF). The app has a button that opens a web browser and navigates to a specific Url. I’m having a hard time verifying that the web browser is opened and the has navigated to the correct url. Katalon doesn’t seem to recognize the web browser. I’ve tried a few options:

  1. com.kms.katalon.core.configuration.RunConfiguration.storeDriver
  2. driver.switchTo().window(winHandle)
  3. WebDriver driver = DriverFactory.getWebDriver()

None of the option seem to work. Since there is no webdriver created. Is there a way to assign a webdriver to the web browser opened by the windows application?
