I am trying to add the PagerDuty datasource to Grafana Helm Chart, however, I am not able to add it successfully as shown below:

It comes up with the error 'Plugin not installed. Not installed plugin with that ID.' The error comes up although I have actually installed the pagerduty plugin, which I enable through the values.yaml file :

I have also enabled the sidecar for datasources as well. My configMap for the pagerduty datasource is as follows:

apiVersion: v1
kind: ConfigMap
metadata: 
    name: pagerduty-grafana-datasource
    labels:
        grafana_datasource: "2"
data:
    datasource.yaml: |-
        apiVersion: 1
        datasources:
            apiVersion: 1
            datasources:
            - name: PagerDuty
              type: xginn8-pagerduty-datasource
              apiKey: XXXXXXXXXXXXXXXXXXXXXXXXX

Not sure what is wrong with this.
