When automating a web page, you need to use the actions in the Browser automation group of actions, and not the UI automation group. The UI automation, such as Click UI element in window are used to automate local applications installed on your machine, and not web pages. You should use Press button in web page for that instead. And for extracting data, you would need to use Extract data from web page or Get details of element in web page.
