JWT Auth share-secret when "running in the cloud"

I read that I could use JWTs for API authentication Authentication and authorization in InfluxDB | InfluxDB OSS 1.8 Documentation

I need to:

  shared-secret = "my super secret pass phrase"

How can I configure that shared-secret when using the hosted “running in the cloud” option?

I can see the option to Generate an API token - is that the same as the shared-secret?
