In the editor field, find the HTML code with the button tag and add an additional field before it.

The structure of templates may vary from theme to theme - it depends on the theme developer. Therefore, this guide may not correspond to the theme used in the store, and you may need to contact our Support or make changes yourself using additional information from the Shopify documentation https://shopify.dev/docs/themes/customer-engagement/email-consent#customer-registration-form-checkbox .
