Hey @Anson , I want to use Opensearch ingest pipeline , how can i specify that in my ClusterOutput, below is my config

apiVersion: <http://fluentbit.fluent.io/v1alpha2|fluentbit.fluent.io/v1alpha2>
kind: ClusterOutput
metadata:
  name: es
  labels:
    <http://fluentbit.fluent.io/enabled|fluentbit.fluent.io/enabled>: "true"
    <http://fluentbit.fluent.io/mode|fluentbit.fluent.io/mode>: "k8s"
spec:
  matchRegex: (?:kube|service)\.(.*)
  es:
    host: opensearch-cluster.default.svc.cluster.local
    port: 9200
    generateID: true
    logstashPrefix: fluent-log-fb-only
    logstashFormat: true
    timeKey: "@timestamp"
    suppressTypeName: "On" 
    httpUser: 
      valueFrom: 
        secretKeyRef:
          name: opensearchpass
          key: username
    httpPassword:
      valueFrom: 
        secretKeyRef:
