CORS Violation

We’re testing the plugin on a dev site (and trial Shopify account). The site is a clean install running the 2021 theme and only WP Shopify installed/activated. We’re receiving this error on the front end when browsing products:

Access to fetch at ‘https://xxxxx.myshopify.com/api/2020-07/graphql’ from origin ‘https://xxxxx.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

I don’t see anything in Shopify about allowing domains. Any thoughts?
