@jasonviviano @willtsai Nick wants to contribute to the documentation for the PodSpec example to use the existing k8s secret. Where is the best place to add this example?

I'd wait for @willtsai ultimately on the answer here but a good place to start as a position would be Kubernetes section under authoring: https://docs.radapp.io/guides/author-apps/kubernetes/overview/ but looking at the PR that's what's already being used!
