How to create secret in pre-install hook & delete after Helm uninstall

I create a K8S Secret with Helm in a pre-install hook.

This secret is a random password for a database user. When I uninstall the Helm Chart I delete the database and the database user, so I'd like to delete the K8S Secret as-well.

Everything works fine, except the secret is not deleted after uninstallation.

apiVersion: v1
kind: Secret
metadata:
  name: secret-name
  namespace: sample
  labels:
    app.kubernetes.io/managed-by: "sample"
    app.kubernetes.io/instance: "sample"
    app.kubernetes.io/version: "1.1"
  annotations:
    "helm.sh/hook": pre-install
    "helm.sh/hook-weight": "-1"
type: Opaque
stringData:
  user: "test-user"
  password: {{ randAlphaNum 10 | quote }}

In the documentation, there is the hook-delete-policy annotation, but the possible values are

In my case, none of the options seem to be right.

How can I automatically delete the K8S Secret at uninstall time?

Why not just use post-delete along with pre-install?

post-delete -- Executes on a deletion request after all of the release's resources have been deleted

annotations:
  "helm.sh/hook": post-delete
  "helm.sh/hook": pre-install
