Python SDK: OpenZiti or Zrok?

I'm confused on my options for a Python SDK. I see one from:
import openziti.

And then also:
import zrok

Seems like two different SDKs. The openziti one seems to be well documented. But the zrok one is harder to find. The blog post announcing it doesn't point to any comprehensive docs or the github source?

The zrok SDK is a superset of the OpenZiti SDK. zrok is based on OpenZiti and uses it for all secure, point-to-point communication. zrok adds a layer of orchestration on top of OpenZiti, but is otherwise a "native" OpenZiti application.

The SDKs in the zrok/sdk tree provide wrappers around the zrok API and it's convenience semantics, and then uses the underlying OpenZiti SDK for all secure communications. You'll see the zrok SDK talk about "shares" and "accesses" (servers and clients, respectively)... these are convenience wrappers around lower level OpenZiti structures like "services" and "identities".

Hope this helps.
