Clcik on link and pop up open, but no progress

I’m running katalon recorder to capture a pop in chrome.

SoftAssert softAssertion = new SoftAssert();
WebUI.openBrowser(‘https://www.google.com/’)
def driver = DriverFactory.getWebDriver()
String baseUrl = “https://www.google.com/
selenium = new WebDriverBackedSelenium(driver, baseUrl)
selenium.open(“https://fagsystem2.test.minpensionssag.dk/pe-fagsystem/test”)
Thread.sleep(5000);
selenium.click(“//button[7]”)
selenium.selectWindow(“”)

When I click the button the pop up appears, but system do not progress to next step and is yellow.
What is the next step to do in katalon recorder ?

I think the command selectPopUp would help, but can you provide me with some images on this issue? What type of popup does the website have?
