I want to build a plugin for my Shopify store to manage orders. What access do I need to the backend and APIs to implement this functionality, and is it possible to achieve this with Shopify’s platform?

I wanted to build a plugin for my Shopify store to manage orders. I tried accessing Shopify’s API to interact with order data and expected to retrieve, update, and manage order information seamlessly. However, I’m unsure if the necessary permissions and access are available through Shopify’s platform, or if additional setup is required.
