How to create delivery customization for extensions only app?

Hey!

We have a extensions-only app where we have delivery customization function.

We tried to deploy it to production, but it looks like we cannot enable it there?
Usually we would just do it with GraphiQL with a mutation. But recently we started seeing that GraphiQL doesn’t have access to functions created by other apps.

We cannot just use dev command to run local graphiql, becuase it’s not a dev store.

What would be a solution to run a createDeliveryCustomization mutation on production store for extensions only apps?

You’ll need to use the authorization flow to obtain an access token so you can make the Admin API request.
