Unable to delete old indices with life cycle policies

Elastic Stack Elasticsearch
1

Hi Team, Small query.
I have created one life cycle policy to delete old indices from Elasticsearch. It is running fine but its not deleting old indices. I am still able to access old indices and able to see the data from old indices.

its very simple delete script.

PUT _ilm/policy/deleteoldindex
{
  "policy": {
    "phases": {
      "hot": {
        "min_age": "0ms",
        "actions": {
          "rollover": {
            "max_primary_shard_size": "5gb",
            "max_age": "2d"
          }
        }
      },
      "delete": {
        "min_age": "2d",
        "actions": {
          "delete": {
            "delete_searchable_snapshot": true
          }
        }
      }
    }
  }
}

Is there any problem with my script / request .

Can you run an explain on one of the indices you think should be deleted?
