I've developed a checkout UI extension-only app, targeting purchase thank-you customer-information render-after. After installing the app in the store and disabling the development store preview in the extensions menu, I ran the following two commands successfully:
npm run build
npm run deploy
However, despite these steps, I'm unable to see my app content on the store. Interestingly, when using npm run dev command, I can see my content, but it disappears once I close it.
Could you provide guidance on how to deploy the code without relying on hosting services? Any insights into resolving this issue would be greatly appreciated. As Shopify mentions that we do not need a server for extension only app.
