Viewer cannot see alert hearts

We have upgrade from old Grafana alert to new Grafana Alertmanager.
We are using Grafana 9.3.6
Now Viewers cannot see hearts and not see items in Alert lists.
I have Admin and can see hearts and Alert list-items.
If I change the Víewer to Admin they can see hearts and Alert list-items

Interesting, probably Viewer does not have enough permissions to use the new API.

We recently developed Grafana HTTP API Data Source, which uses API Keys or Tokens to retrieve alerts and annotations from the Grafana instance and can be an option to display annotations and Alerts for Viewers - it’s actually an interesting use case!

Do you think this can be solved so Viewers can get alerts?
