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