Unable to select target field

Hi, I tried numerous times to capture the target field to anchor info for the Unicorn exercise but simply can’t.

I watched the video and followed step by step. Each time the Chrome page comes up with the unicorn name generator page, I try to capture and it never does. Instead, the green target box pops up & captures the automation page which I am setting up.

After Clicking on Select Target, if you want to switch windows or do any other operation to open a page where the target is located, press “F2” key…This gives you 5 seconds of time to do any actions before the green target selector is active again.
