Adding entry point, different procedure than v2?

Traefik Traefik v3 (latest)

In v2, I could add an entry point by using this yaml on top of the Helm chart:

ports:
  proxy:
    port: 6809
    expose: true
    exposedPort: 6809
    protocol: TCP
additionalArguments:
- "--entrypoints.proxy.address=:6809/tcp"

For v3, I have updated the yaml to this:

ports:
  proxy:
    port: 6809
    expose:
      default: true
    exposedPort: 6809
    protocol: TCP
additionalArguments:
- "--entrypoints.proxy.address=:6809/tcp"

yet I can't seem to punch through to the receiving service. I tried looking in the migration docs, but I found nothing which seemed relevant to this. Any ideas?
