Provision BigQuery datasource

Hello,

I am trying to provision a BigQuery datasource following the instructions detailed here. However, in my case I am using GCE Default Service Account authentification and the documentation does not provide examples of such provision file.
I tried with the following file:

apiVersion: 1

datasources:
- name: test
  type: doitintl-bigquery-datasource
  access: proxy
  jsonData:
     authenticationType: gce

But my dashboard returns “Datasource named test was not found”. Does anyone has experience with such datasource provisioning?

Thanks!
