I need to create a GCP object storage sink & using the Lenses connector. I am required to use authentication keys within a file.

In the documentation, I can see that `connect.gcpstorage.gcp.auth.mode=File` is available; my question is this: where does the file need to be stored in order for the connector to use it?

Should the file path I provide with `connect.gcpstorage.gcp.file` be a file path on the Connect Worker? On Lenses itself?

when you login to gcp console using `gcloud auth application-default login` the credentials file is saved under ~/.config/gcloud. Or you can export the api key linked to a service account and give it the path to that
