I have submitted a Shopify Application. And got the review as follows:
Attempt to implement an automated installation process like ScriptTags or Assets APIs to make the installation process faster and simpler for merchants. Include manual instructions for these automated processes in the app's user interface. Automating storefront installation is important because requiring merchants to change their theme's code doesn't support good merchant experience.
I have searched online, read the document (link), and also searched on YouTube but didn't get the exact way or any code snippet about How to achieve automatic installation process. Can someone please guide me?
