DigitalOcean App expose API Schema

I’m running a DigitalOcean App as our team’s backend dev server so that the frontend team doesn’t need to keep pulling updates from the backend, but I need to expose the API schema (ie graphql playground). But I’m not sure how to do it. We can query the backend just fine but we are accustomed to navigating to the api endpoint URL to view the available Schema. Any help is appreciated. I have this defined in my spec file:

ingress:
  rules:
  - component:
      name: frontend
    match:
      path:
        prefix: /
  - component:
      name: backend
      preserve_path_prefix: true
    match:
      path:
        prefix: /admin
  - component:
      name: backend
      preserve_path_prefix: true
    match:
      path:
        prefix: /admin-api
  - component:
      name: backend
      preserve_path_prefix: true
    match:
      path:
        prefix: /health
  - component:
      name: backend
      preserve_path_prefix: true
    match:
      path:
        prefix: /shop-api
