Rename the kubernetes prometheus service

i)What i am getting- i am creating prometheus by using helm release of prometheus and using this repo "https://prometheus-community.github.io/helm-charts" so i am getting the services name like this 1)prometheus-kube-prometheus-operator 2)prometheus-kube-state metrics 3) prometheus-grafana, etc.
ii)What i am expecting- 1)prometheus-operator 2)state metrics 3)grafana, etc.
iii)Where i am stuck- As i am using this repo i am giving name only in helm release of prometheus name=“prometheus” so i think the suffix coming from repo only , how can i make them to what i want.
