How to access Gemini API using a workspace account?

Hello,

I need to access Gemini API using a HIPAA compliant workspace account.

I created a google workspace, and logged in to GCP with the same workspace admin account.

I generated an API key on GCP, but I want to make sure I am using the version of Gemini which is linked to my workspace account, and is HIPAA compliant.

I am using Gemini in a server to server scenario, so using OAuth is out of scope if I had to guess.

Any suggestions on would be appreciated.

Thank you
