What is the Tempo datasource for Grafana after installing the tempo-distributed helm chart?

Grafana Configuration
1

I deployed the tempo-distributed Helm chart and I am receiving trace spans from a test microservice.

I am trying to visualize the traces via Grafana 8.0 deployed in the same K8 cluster. I can not get grafana to setup that datasource. Which of the services created by tempo-distributed and the port is the one to be used?

Attached are the services created.

Thanks

It has been more than 2 weeks after this question, and nobody cares to reply?
