When I use the theme app extension, there is an extension folder where my app, which is my React app, is located, which is in the assets folder, the app.css and app.js files, and also the liquid files are in the block and snippets folders. Now when I do shopify app dev and go into edit theme in shopify, in the state where I installed my app, I can add and display this app in the embedded app price. But now my problem is that I want to deploy it. When I deploy and create its version, I go to select the embedded app, I select it but it does not display. The page is blank. It does not read my app.js and app.css at all. I want to use it for the app proxy so that when I send a request to that api /apps/myapp, it shows me the information about the shop that installed it. What should I do now?
