What Katalon settings need to use for PushNotifications for make them appear

TestCase:
WebUI.openBrowser(’’)
WebUI.maximizeWindow()
WebUI.navigateToUrl(GlobalVariable.url_base + ‘/pn/pnhttp.html?isAutomationCheck=false’)
= Here I will click on Allow in Chrome pushnotification with robot.framework, because google notification doesnot have xpath
// Pushnotification with Advertisement appear in browser window
= Here clicking on Advertisement window
= Verify redirect advertisement page

But when I click on Allow button, nothing happens
When I’m trying do it outside Katalon it’s working fine

What settings I need to type in Katalon for make this Testcase real?
