I have created an app in "Meta for developers" and followed the steps to create a long-lived access token for this app to be able to post to IG through a react app I have. It works to create carousel items and publish it, it shows up on my IG. But when I add the attribute "product_tags" and try to publish it says that the product id is not valid. I have created an Instagam shop and added the products so that shouldn't be the issue. However, it says in the documentation that

"If creating containers for product tagging, the app user must have an admin role on the Business Manager that owns the IG User's Instagram Shop."

How do I give this app that I created an admin role?
