Paste the code to you Elementor website’s HTML field.
Next, go to your Elementor website and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on Elementor’s dashboard. Add it to your page, and paste the code you’ve copied before to the HTML field. Save and update, and that’s it, you should have Common Ninja’s Process widget on your Elementor website.
