Support Google BigQuery

I successfully made a dashboard that can connect to BigQuery and published to web, but only on a gcp windows vm. On power bi desktop, I created a dashboard and successfully connect to BigQuery. After publishing to power bi server, it requires credential again. But the authentication method is limited to 'basic', except on the gcp windows vm. On the vm, the authentication method is limited to 'OAuth2'. I can only provide credential on that gcp vm. Anyone experiencing this as well?
