Question on SSO Integration with google workspace

Can you help me understand some of the pricing? I have a customer who uses google Workspace and needs to login with SSO using their google workspace.

In order to do this, from what I understand I have a few options:

  1. Use Self-service SSO, configure the info, and then send ticket to client. This requires a B2B professional or enterprise plan, since it’s only one customer it’s not worth the cost and I won’t go this route.

  2. Add a new “google workspace” enterprise connection. This requires gathering the client information to use with configuration. This would require me to be on a B2B Essentials plan? Then, add this connection to my Auth0 application.

  3. Set up a new SSO Integration and choose “google workspace”. Then, same as in step 2, input client information and be on a B2B Essentials plan. Add this connection to my Auth0 application.

From what I understand, 2 and 3 are the exact same thing in the backend, just a different way to set it up, is that true?

Let me know if anything I’m listed is inaccurate. I’m more curious about cost. Also curious if an SSO integration can be added as a connection to my Auth0 application? I’m referring to the “connections” tab where it shows “enterprise”.

Thanks!
