Provision contact points on docker grafana:10.0.3

Good day, I’m having issues where a provisioned contact point is not showing on the Grafana UI (docker 10.0.3). I placed the below notifiers.yml file inside my /provisioning/notifiers folder:

apiVersion: 1
contactPoints:
  - orgId: 1
    name: cp_1
    receivers:
      - uid: first_uid
        type: prometheus-alertmanager
        disableResolveMessage: false
        settings:
          url: http://test:9000
deleteContactPoints:
  # <int> organization ID, default = 1
  - orgId: 1
    # <string, required> unique identifier for the receiver
    uid: first_uid
