Slack Notification is not working

I have added the slack token in secret and changed the configmap but still no notification triggered.

The config I am using

`` ` apiVersion: v1
kind: ConfigMap
metadata:
name: argocd-notifications-cm
data:
trigger.on-sync-status-unknown: |
- when: app.status.sync.status == 'Unknown'
send: [app-sync-status]

template.app-sync-status: |
message: |
Application {{.app.metadata.name}} sync is {{.app.status.sync.status}}.
Application details: {{.context.argocdUrl}}/applications/{{.app.metadata.name}}.

service.slack: |
token: $slack-token
---
apiVersion: v1
kind: Secret
metadata:
name: argocd-notifications-secret
stringData:
slack-token: ```

Start by reviewing the supplied ConfigMap and Secret, then inspect how notification triggers and Slack service configuration are loaded and evaluated. Reproduce the configuration in a Kubernetes environment and check controller logs; done means the sync-status trigger reliably produces the configured Slack notification.
