Filtering Notification by user backend roles

Plugins Alerting
1

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
Version 2.18, issue happened after upgrading (destinations migrated to notifications)

Describe the issue:
Before upgrading, i was filtering alerting (alerts, monitors and destinations) by user backend roles, as documented here: Alerting security - OpenSearch Documentation.

PUT _cluster/settings
{
  "transient": {
    "plugins.alerting.filter_by_backend_roles": "true"
  }
}

After upgrade, destinations were replaced by notifications plugins and i’m not able to see/filter notifications anymore.

Adding the follow cluster permissions, i’m now able to see notifications again:

cluster:admin/opensearch/notifications/channel/get
cluster:admin/opensearch/notifications/config/create
cluster:admin/opensearch/notifications/config/get
cluster:admin/opensearch/notifications/config/update

But now every user can see (and modify) any notifications, without any filter.

Do you have any further documentations about that?
Is still possible to filter notifications like destinations?
