Currently, it displays an alert when clicked, but it's designed to be easily modified for more advanced functionality.\n\n## Modifying the Help Widget\n\nThe help widget is implemented in a modular way through the `getHelpWidgetHtml()` function. To change its appearance or functionality:\n\n1. Locate the `getHelpWidgetHtml()` function in the code\n2. Modify the HTML, CSS, or JavaScript as needed\n3. The widget's functionality is contained within the embedded script tag\n\n## Implementation Details\n\n- The proxy uses standard fetch API to forward requests\n- URL transformation handles both absolute and relative URLs\n- The widget is injected before the closing `` tag when
