Trying to set elastic user password in ECK 2.6.1

[screwyy]

Hello,

I'm trying to set the elastic user password as described here and here

I receive the following error:

"unknown secure setting [elastic] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"

I used this code which is similar to what the operator creates

---
apiVersion: v1
kind: Secret
metadata:
  name: logging-es-elastic-user
type: Opaque
data:
  elastic: Q2FPYlFGNjVhMDYxVTAxc0lmdDZ4MTBq

and based on the docs tried this:

---
apiVersion: v1
kind: Secret
metadata:
  name: logging-es-elastic-user
type: kubernetes.io/basic-auth
stringData:
  username: elastic
  password: parola

and the error is at the operator

"Secret \"logging-es-elastic-user\" is invalid: [data[%s][username]: Required value, data[%s][password]: Required value]"

by default, created by the operator it looks like this:

kubectl -n logging get secret/logging-es-elastic-user -oyaml
apiVersion: v1
data:
  elastic: Tzg0V08zNDJUaTdWMTRkT2ZGNjdRT0hE
kind: Secret
metadata:
  creationTimestamp: "2023-02-07T12:57:28Z"
  labels:
    common.k8s.elastic.co/type: elasticsearch
    eck.k8s.elastic.co/credentials: "true"
    eck.k8s.elastic.co/owner-kind: Elasticsearch
    eck.k8s.elastic.co/owner-name: logging
    eck.k8s.elastic.co/owner-namespace: logging
    elasticsearch.k8s.elastic.co/cluster-name: logging
  name: logging-es-elastic-user
  namespace: logging
  resourceVersion: "377972498"
  uid: b319b016-8ef3-49d7-9099-fbbac49c2405
type: Opaque

Tried also with bootstrap.password like this:

---
apiVersion: v1
kind: Secret
metadata:
  name: logging-es-elastic-user
type: Opaque
data:
  bootstrap.password: Q2FPYlFGNjVhMDYxVTAxc0lmdDZ4MTBq

and the error in elasticsearch container is:

"error.message":"unknown secure setting [elastic] please check that any required plugins are installed, or check the breaking changes documentation for removed settings"

So it's overwriting my bootstrap.password with elastic...
So how should the code look like?
