Windows Desktop App - Unable to capture drop-down list item

I’m using Katalon Studio 8.2.5 on Windows 10.
Recording a Windows app and I can capture a drop-down labeled as a combobox and use the click action on it to display the items in the list. But I cannot record or capture an individual item from the list using the recorder or when using Spy Windows Object

Question: How do I capture a specific item from the list using the recorder? Using Spy Windows Object I can only capture elements in the first window. How can I move to another window when using Spy Windows Object for a Windows app?
