How to look for query logs and response time?

Hello, we had set up two elasticsearch clusters, one is for our stg app and the other one is to send the logs.

If a go to Observability and to logs streams, i can see the logs, but seems to be cluster logs.

I had enabled the slow query, but still not able to see our app logs queries

This is how it looks now:

And for all indexes slow query cfg:

"search": {
          "slowlog": {
            "threshold": {
              "fetch": {
                "warn": "1s",
                "trace": "200ms",
                "debug": "0s",
                "info": "800ms"
              },
              "query": {
                "warn": "10s",
                "trace": "500ms",
                "debug": "0s",
                "info": "5s"
              }
            }

There is something wrong configure or i missing something else?

Thanks
