2. Click on the “Main Camera”
3. Show the UI Toolkit Debugger on the Inspector by clicking on the Window menu button (3 dots menu on the top-right corner of the Inspector) and click UI Toolkit Debugger.
4. In the Inspector, scroll down to the “New Behaviour Script” attached to it in the Inspector window
5. Right-click on the “X” or any other value label (See attached GIF)
