Google API Service Account - Can't Access Private Data

Question

Trying to access my personal calendar data using a service account.

I've gone through the setup for creating a service account (with owner permissions). Using NodeJS, I've successfully made requests to my public calendar, but not my private calendars. ( the same result using googleapis and google-OAuth-jwt packages)

Everything that I've searched shows that I need to give "domain-wide authority", BUT, I do not have a G Suite account, so I don't believe this applies to me.

So the question is, can one access their own personal calendar data using a service account? What might I be missing?

Remember service accounts are not you. The service account has its own Google calendar account so if you are trying to read one of your personal calendars you are going to have to share it with the service account.

Shared the calendar with my service account.
