Using recording rules in Grafana for the loki data source

I’ve setup a data sourced managed recording rule in the grafana alerting ui that queries loki.

My understanding is that this should create metrics that can be used by other parts of grafana, is this true?

If so do I need to do anything extra to get these metrics forwarded to a data store like mimir so they can be used?

I’ve installed loki and grafana by helm charts if that makes a difference.

If it helps anyone else, the bit I was missing was adding to the remote_write section add_org_id_header: false
