I have started learning Shopify app development and have learned many things, but now I am stuck on changing the styles of product variations. Shopify requires that your app should have a theme app extension so your app won't leave ghost code behind when uninstalled. (simplified e.g) I have seen many apps with the same functionality that I want. For example, "The main App page will allow users to change the style of variations, and after that, users have to save the changes. Then, if the App is enabled from the App embed section, only then will it change the appearance of Product variations." You can check out Globo Color Swatch, which I like. 2 Questions: I currently don't understand how all this works, like where I need to make changes. (In the main App or in the Theme app extension?) I want to know how I can change the styles of product variations (like shape, size, hover effect) using theme app extension or App or Both 🥹. I am using Shopify Remix template not node. Any help would be appreciated! 1: I have tried the Rest api that creates product variations or updates it but it won't and can't change the styles.
