Not able to filter logs with pod labels after moving from promtail to Open-telemetry collector

I was using promtail to send logs to loki. I had option to filter logs with pod label. Like

app=appname

But now, after switching to otel collector, I have to search logs like this.

{k8s_container_name=“bffapi”}

Each log line has these pod labels in them. Is there any way I can search with these pod labels from grafana?

I know this might be a dump question, but please help. Iam stuck here.
