The Show Elements button in the Computer Vision wizard is used to highlight all UI elements that have been identified by the Computer Vision analysis. This helps you to see the UI elements that are available for automation and to select the ones that you want to use in your activities. The Show Elements button is located in the top-right corner of the Computer Vision wizard. When you click it, the UI elements are highlighted with different colors and shapes, depending on their type and category. You can hover over each UI element to see its name and properties. You can also use the Filter Elements button to filter out specific UI elements from being processed by the Computer Vision engine.
