You press the "record" button below the code, then interact with your app, and every time you tap or scroll or type something, a code line appears in the code panel.
Finding and interacting with Web elements based on a readable path based on ID or class does not work well. Interacting with elements is easy only when you can find them by text, but if there's no text in the element, sometimes the only way to work with it is using very long and unreadable relative paths.
