Hi  
I deployed an Azure Elasticsearch Self-Managed cluster. According to our Dev team, we need to enable CORS by adding these settings into the Configuration File yaml:

```auto
    "http.cors.enabled": true,
    "http.cors.allow-origin" : "*",
    "http.cors.allow-methods" : "OPTIONS, HEAD, GET, POST, PUT, DELETE",
    "http.cors.allow-headers" : "Authorization,X-Requested-With,X-Auth-Token,Content-Type

```

I tried using the API by login to the GUI and going to the Dev Tools and API Console, and then running this:

```auto
PUT /_cluster/settings
{
  "persistent" : {
    "http.cors.enabled": true,
    "http.cors.allow-origin" : "*",
    "http.cors.allow-methods" : "OPTIONS, HEAD, GET, POST, PUT, DELETE",
    "http.cors.allow-headers" : "Authorization,X-Requested-With,X-Auth-Token,Content-Type, Content-Length"
  }
}

```

But I get an error saying that I can't update those dynamically.  
The documentation says that I can add these lines into the configuration yaml file, but I'm having trouble understanding on which Node I should modify/add this.  
Should I ssh to every node (Master, Client, Data) and add these lines? Or only the Master nodes? Or only the Client node and that will get these propagated?

Thanks in advance
