How can I create a CCPA compliant 'Do Not Sell My Information' link?

I know that when you sign up for emails, there is an opt out for those. But for the CCPA you have to have a link that allows you to opt out of having your information sold. Is it a 3rd party app that you have to install or is it a form that you make yourself. I have no code experience so if it’s that then I’m really lost. I would just like a link to the do not sell my information page where they put their first and last name in, as well as their email.

It’s a free app provided by Shopify.

What’s the name of the app?
