How to trigger an error if an image is still there? (or: Wait until image disappears)

Here is the solution with “visualSearch”. The macro waits until the blue banner disappears OR until the timeout of 60 seconds is reached. At t=21s in the video I click the button to hide the banner => macro no longer finds image and ends loop.

Code:
