Grafana alert/notifier not showing in contact points

I'm currently setting up a new Grafana with the latest version and helm chart. I added a notifier so alerts are send to a microsoft teams channel. The notifiers.yaml can be found in the running container in 'etc/grafana/provisioning/notifiers'

Unfortunately it does not appear in 'contact points'.

The part of the helm chart regarding notfiers looks like this

notifiers: 
 notifiers.yaml:
   notifiers:
   - name: sa-roemoe-notifier
     type: teams
     uid: lnc31CJGz
     org_id: 1
     is_default: true
     settings:
       url: <<myTeamsUrl>>

Is there something wrong with it? Since it already is in the running container I assume I made a mistake but I can't figure it out.

Best regards.
