Problem with create contact point/notifiers (Grafana 8.5.0 and helm charts)

I’m using helm chart in version 5.8.16
and Grafana in version 8.5.0.
When I add in values.yaml:

notifiers:
  notifiers.yaml:
    notifiers:
      - name: notification-channel-1
        type: email
        uid: notifier1
        org_id: 1
        send_reminder: true
        frequency: 1h
        disable_resolve_message: false
        settings:
          addresses: xxx@xx.xx
          singleEmail: false
          message: my optional message to include
          subject: Test subject

After deploy I see file in pod grafana file /etc/grafana/provisioning/notifiers/notifiers.yaml with content. But I don’t have new contact point in grafana UI.
