I have an installed app in my Shopify website, zakeke ..it's a 3D customized tool. the ui for the app in my website is very basic and I want it upgraded. there's a way to upgrade it which requires a hosted page to be loaded via i frame into my Shopify product page. so I also have the required ui in figma which I need to implement. Been trying but don't know how to do it. This will be Paid project. The app and process of UI development is well documented and its based on react from what I understand.
