Adding a new label while parsing logs with Promtail

I have instance of Promtail, Loki and Grafana running. Following is my Promtail configuration

scrape_configs:
- job_name: docker_logs
  docker_sd_configs:
    - host: unix:///var/run/docker.sock
      refresh_interval: 10s
      filters:
        - name: label
          values: ["logger=loki"]
  relabel_configs:
    - target_label: 'job'
      replacement: 'docker'
    - source_labels: ['__meta_docker_container_name']
      regex: '/(.*)'
      target_label: 'container'

positions:
  filename: /tmp/positions.yaml
clients:
  - url: http://loki:3100/loki/api/v1/push
server:
  http_listen_port: 9080
  grpc_listen_port: 0

It's running as expected, but I want to add a new label "Level" by parsing the logs of containers. Following is the sample of some logs lines. For example, if line contains INF or INFO, level=INFO OR if log contains ERR/ERR, level=ERROR

[11:26:05 INF] CalculatedValues Notification was successfully produced for unit:
[02/04/2025 05:29:05 INF] Kafka connection successfully.
trce: Grpc.AspNetCore.Server.ServerCallHandler[18]
dbug: Grpc.AspNetCore.Server.ServerCallHandler[15]

How can I configure Promtail? I am quite new to Promtail and any help or suggestion would be great.
