How do I expose multiple ports between containers?

Question

(Search on here returns zero i'm afraid)  
I have a basic use case where a container (Qdrant) needs to expose 2 ports (6333 and 6334) to the backend container.  
It would look like this in a docker compose:

```dockercompose
  qdrant:
    image: qdrant/qdrant:latest
    container_name: myApp-qdrant
    ports:
      - "6333:6333"
      - "6334:6334"
etc...
```

I can't seem to work out how to do this in railway.   
I have found the settings for external networks only.  
Any help appreciated.
