'bash: argocd-vault-plugin: command not found' Needed help in using Azure Key Vault with ArgoCD

[MeghaSuresh122]

Describe the bug
I'm new to DevOps and I came across ArgoCD couple weeks ago. I've been using CI/CD Azure pipelines and I would like to switch CD to ArgoCD. I followed the steps in docs to integrate Azure Key Vault with ArgoCD, but it is not fetching values from the Key Vault. I think there is something wrong with my installation, Can someone please help with it? When execing into repo-server pod, and running argocd-vault-plugin --help returns:
bash: argocd-vault-plugin: command not found
But ls cmp-server/plugins lists argocd-vault-plugin.sock.

To Reproduce
Steps to reproduce the behavior:
Argocd-vault-plugin installation: #https://argocd-vault-plugin.readthedocs.io/en/stable/installation/#initcontainer-and-configuration-via-sidecar

vault-configuration:

apiVersion: v1
kind: Secret
metadata:
  name: vault-configuration
  namespace: argo-cd
data:
  AVP_TYPE: YXp1cmVrZXl2YXVsdA== # azurekeyvault
  AZURE_TENANT_ID: <base64-tenant-id>
  AZURE_CLIENT_ID: <base64-client-id>
  AZURE_CLIENT_SECRET: <base64-client-secret>
type: Opaque   

cmp-plugin:

apiVersion: v1
kind: ConfigMap
metadata:
  name: cmp-plugin
  namespace: argo-cd
data:
  avp.yaml: |
    apiVersion: argoproj.io/v1alpha1
    kind: ConfigManagementPlugin
    metadata:
      name: argocd-vault-plugin
    spec:
      allowConcurrency: true
      discover:
        find:
          command:
            - sh
            - "-c"
            - "find . -name '*.yaml' | xargs -I {} grep \"<path\\|avp\\.kubernetes\\.io\" {} | grep ."
      generate:
        command:
          - argocd-vault-plugin
          - generate
          - "."
          - "-s"
          - "argo-cd:vault-configuration"
      lockRepo: false

      volumeMounts:
        - mountPath: /custom-tools

  volumes:
   - name: cmp-plugin
     configMap:
       name: cmp-plugin
   - name: custom-tools
     emptyDir: {}

  serviceAccount:
    create: true
    name: "" # "argocd-repo-server"
    annotations: {}
    labels: {}
    automountServiceAccountToken: true

  rbac:
    - apiGroups:
        - ''
      resources:
        - secrets
        - configmaps
      verbs:
        - get
        - list
        - watch

Expected behavior
Need to replace <password> with password key value from the vault named azure-key-vault.

kind: Secret
apiVersion: v1
metadata:
  name: test-secret
  namespace: django
  annotations:
    avp.kubernetes.io/path: "azure-key-vault"
type: Opaque
stringData:
  password: <password>

Additional context
I've used Sealed Secrets for my secret variables till now and it worked fine. I want to know that whether fetching values directly from Azure Key Vault is better than using Sealed Secrets.
