There aren't any plugins for UI automation. You need to make a custom code and download a job to put into the libraries. If it were panelized, then it would be straightforward. It should be in a panel of the tools, so you can add those tools as your test step in your test cases. For example, it would be nice to have a Selenium plugin available from the menu, where I can select "open browser" and provide the URL. That URL would be immediately open in the browser. This is like a keyword, and then the Selenium plugin should be there.
