Describe the bug
I want to use kustomize with helm chart for some additional patching in chart, one way I found is to config- management plugin ,which need to be defined in Argo-CD cm.

ArgoCD-CM

configManagementPlugins: |
    - name: kustomized-helm
      init:
        command: ["/bin/sh", "-c"]
        args: ["helm dependency build || true"]
      generate:
        command: ["/bin/sh", "-c"]
        args: ["echo \"$HELM_VALUES\" | helm template . --name-template $ARGOCD_APP_NAME --namespace $ARGOCD_APP_NAMESPACE $ARGOCD_ENV_HELM_ARGS -f - --include-crds > all.yaml && kustomize build"]

-- Here is my appset file where I am using the kustomized-helm plugin

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: loki-rule-stack
spec:
  generators:
  # only remote clusters
  - clusters:
      selector:
        matchExpressions:
        - key: environment
          operator: In
          values:
            - "infrastructure"
  template:
    metadata:
      name: '{{"{{"}}name{{"}}"}}-loki-rule'
      namespace: argocd
      finalizers:
      - resources-finalizer.argocd.argoproj.io
    spec:
      destination:
        name: '{{"{{"}}name{{"}}"}}'
        namespace: monitoring
      project: default
      source:
        path: apps/lokiruleset
        repoURL: https://github.com/myorf.demo.git
        targetRevision: HEAD
        plugin:
          name: kustomized-helm
          # env:
          #   - name: HELM_VALUES
          #     value:  |
          #       skipCrds: true
          #       values: values-new.yaml
          #       release-name: cortex-loki
         helm:
           releaseName: cortex-loki
           skipCrds: true
           valueFiles:
             - 'values-{{"{{"}}name{{"}}"}}.yaml'
      syncPolicy:
        automated:
          prune: true
          selfHeal: false

• I wanted to use custom values file for different env, but I am not able to defined it with environment variable for the customized plugin option , so I tried to use default helm section to define valuesfiles, but getting error:

• It seems that it is not allowing to use helm section if you are using configuration plugin

rpc error: code = Unknown desc = Manifest generation error (cached): multiple application sources defined: Helm,Plugin

To Reproduce

• First configure config plugin in argo-cd configmap

argocd-cm.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    app.kubernetes.io/name: argocd-cm
    app.kubernetes.io/part-of: argocd
  name: argocd-cm
  namespace: argocd
data:
  configManagementPlugins: |
    - name: kustomized-helm
      init:
        command: ["/bin/sh", "-c"]
        args: ["helm dependency build || true"]
      generate:
        command: ["/bin/sh", "-c"]
        args: ["echo \"$HELM_VALUES\" | helm template . --name-template $ARGOCD_APP_NAME --namespace $ARGOCD_APP_NAMESPACE $ARGOCD_ENV_HELM_ARGS -f - --include-crds > all.yaml && kustomize build"]

• Then Create application or appset on Argo-CD and used plugin name :

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: loki-rule-stack
spec:
  generators:
  # only remote clusters
  - clusters:
      selector:
        matchExpressions:
        - key: environment
          operator: In
          values:
            - "infrastructure"
  template:
    metadata:
      name: '{{"{{"}}name{{"}}"}}-loki-rule'
      namespace: argocd
      finalizers:
      - resources-finalizer.argocd.argoproj.io
    spec:
      destination:
        name: '{{"{{"}}name{{"}}"}}'
        namespace: monitoring
      project: default
      source:
        path: apps/lokiruleset
        repoURL: https://github.com/my-org/test.git
        targetRevision: HEAD
        plugin:
          name: kustomized-helm
          helm:
           releaseName: cortex-loki
           skipCrds: true
           valueFiles:
             - 'values-{{"{{"}}name{{"}}"}}.yaml'
      syncPolicy:
        automated:
          prune: true
          selfHeal: false

Expected behavior

It should allow to use helm section also in appset for passing custom values file
