Opensearch cluster RED and not able to delete the RED old .opendistro indices

OpenSearch

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
opensearch version 2.9.0
opensearch_dashboards version 2.9.0

Describe the issue:
The issue here is we were upgrading the cluster and unforunatley 75% of the nodes went down.
Now we managed with the remaining upgrade, but after upgrade the cluster is RED due to two indices not found (.opendistro-anomaly-detectors AND .opendistro-reports-instances).
Now I tried to delete those indices with admin credentials, but getting the below response

{
  "error": {
    "root_cause": [
      {
        "type": "security_exception",
        "reason": "no permissions for [] and User [name=elastic, backend_roles=[], requestedTenant=null]"
      }
    ],
    "type": "security_exception",
    "reason": "no permissions for [] and User [name=elastic, backend_roles=[], requestedTenant=null]"
  },
  "status": 403
}

The user elastic is the admin user and I have ran out of ideas to delete this index.
Tried via command line and via UI.

Can anyone help?

You would have to use the tls certs/keys for authentication ie:

curl -k --cert ./admin.pem --key ./admin-key.pem -XDELETE 'https://localhost:9200/.opendistro-alerting-config'
