Access CronWorkflow name for metrics labels - kustomize

Question

I have a CronWorkflow that sends the following metric:
apiVersion: argoproj.io/v1alpha1
kind: CronWorkflow
metadata:
name: my-cron-wf
spec:
schedule: "0 * * * *"
suspend: false
workflowSpec:
metrics:
prometheus:
- name: wf_exec_duration_gauge
help: "Duration gauge by workflow name and status"
labels:
- key: name
value: my-cron-wf
- key: status
value: "{{workflow.status}}"
gauge:
value: "{{workflow.duration}}"
I would like to populate the metric's label name with the CronWorkflow name using a variable in order to avoid copying it but I didn't find a variable for it.
I tried to use {{workflow.name}} but it equals to the generated workflow name and not to the desired CronWorkflow name.
I use Kustomize to manage argo workflows resources so if there is a kustomize-way to achieve this it would be great as well.

Argo Workflows automatically adds the name of the Cron Workflow as a label on the workflow. That label is accessible as a variable.
apiVersion: argoproj.io/v1alpha1
kind: CronWorkflow
metadata:
name: my-cron-wf
spec:
schedule: "0 * * * *"
suspend: false
workflowSpec:
metrics:
prometheus:
- name: wf_exec_duration_gauge
help: "Duration gauge by workflow name and status"
labels:
- key: name
value: "{{workflow.labels.workflows.argoproj.io/cron-workflow}}"
- key: status
value: "{{workflow.status}}"
gauge:
value: "{{workflow.duration}}"
