Add a gitlab-ci dashboard to grafana

Hi all,

I enabled Grafana today because I intend to create a Gitlab CI integration, where we see all our pipelines and if they failed. I am new to Grafana, but I found that the pipeline info is not in Prometheus dataset that is added by default. I guess I need to add Postgres to achieve my goal?

Has anyone done something similar and could lead me to some good ressource, because honestly I am quite lost on where to start.
