Did you try this for mapping?
Otherwise you can use this to handle the window
Is this a reproducible step ?
Use ObjectSpy with the arrow pointer, perform you test steps manually to reporduce the pop up and when present on the screen - capture it
If you are using a web app, then in this example https://www.w3schools.com/css/tryit.asp?filename=trycss_tooltip you can modify the property value visibility: hidden; to visibility: visible; which will enable the tooltip to be shown. You can then capture this via TC, this is how I go about capturing the tooltip on the web app that I test (via Chrome DevTools and modifying the HTML code).
Unfortunately the same can not be done with desktop apps.
