Setting up Shopify API integration?

Correct me if I’m wrong, though, but this does still look like it’s specific to one shop. Is there a way to allow this to be agnostic to shops? (i.e. would redirect to Shopify’s auth, the user would log in to their shop, authorize a Shopify app that would be linked to the Retool tool, and then would return to the Retool tool with the access token)
