Hey team! I am building a post-purchase upsell on the Thank You page with checkout_ui as an extension type. I have declared all of my access scopes in the app.toml file, and the query to fetch order details works perfectly fine on GraphQL, but throws an error in the network tab. Am I missing somethi…

When using query, you’re querying the Storefront API with these unauthenticated access scopes , which means you’re not able to access any order or customer data.
