Unable to click submenu item for desktop applications

Hi @chandan.kumar,

As you said, it still can be clickable by using Action Builder. So I would suggest you try to click in this way (using Action Builder in Katalon).

import org.openqa.selenium.WebElement
import org.openqa.selenium.interactions.Actions

WebElement submenuItem = Windows.findElement(findWindowsObject('Object Repository/Mic 01/Submenu_Item'))

Actions builder = new Actions(Windows.getDriver());
builder.click(submenuItem)
builder.perform()

And about the submenu item object, maybe you have to write its locator on your own, as both Windows Recorder and Native Windows Recorder were not able to capture it.

~ Hope it could help! /=)
