Display the Quiz

With the quiz editor screen still open, click on the quiz shortcode (on the right) to select it and then press Ctrl+C (Windows) or Cmd+C (Mac) to copy it.
Now you can embed it to any post or page you want. Just create a new post (or open an existing one) and paste the shortcode in the content editor (doesn’t matter if Gutenberg or Classic) on a new line with Ctrl+V (Windows) or Cmd+V (Mac).
