How to install prometheus exporter plugin to openSearch in helm managed environment

Question

I want to collect metrics from my opensearch

I've found this plugin https://github.com/aiven/prometheus-exporter-plugin-for-opensearch

My current definition looks like this:

chart.yaml:

  - name: opensearch
    version: 1.8.0
    repository: https://opensearch-project.github.io/helm-charts/

values.yaml:

opensearch:
  plugins:
    enabled: true
    installList:
      - what should I write here ?

  addIndexedAt: true
  clusterName: ...
  masterService:...
  resources:
    requests:
      cpu: 500m
      memory: 1000Mi
    limits:
      cpu: 3000m
      memory: 2000Mi
