Lab: Reflected XSS into a template literal with angle brackets, single, double quotes, backslash and backticks Unicode-escaped

1. Submit a random alphanumeric string in the search box, then use Burp Suite to intercept the search request and send it to Burp Repeater.
2. Observe that the random string has been reflected inside a JavaScript template string.
3. Replace your input with the following payload to execute JavaScript inside the template string: ${alert(1)}
4. Verify the technique worked by right clicking, selecting "Copy URL", and pasting the URL in the browser. When you load the page it should trigger an alert.
