2. Create an unlocked promotion with a "CTA" layer (outlined in blue below).
3. Find the URL for the account registration page of your website and paste it into the "Link URL" of your CTA layer (outlined in red above). If you click on the "CTA" layer in the design canvas the options for it will appear on the right side of the page. Here is an example of a possible account registration page URL on a Shopify site: https://reallycoolstore.myshopify.com/account/register

Then select the "Does Not Exist" option from the dropdown next to it. These options are shown below outlined in red.
