How to update admin password in internal_user.yml file without losing the existing users

@pablo @jasonrojas

Could you please help in resetting admin password

Process that I tried .

  1. modified values.yaml for helm chart of opensearch
  2. generated password using hash.sh and then updated the internal_user.yml and ran securityadmin.sh -like this -sh securityadmin.sh -cd …/…/…/config/opensearch-security/ -ilc -nhnv -cacert /usr/share/opensearch/config/root-ca.pem -cert /usr/share/opensearch/config/kirk.pem -key /usr/share/opensearch/config/kirk-key.pem
  3. tried using openserach-dashboard as well but getting " resource admin is read-only"

Please help me in fixing this issue . I am doing using helm chart
