Thank you very much for the PR Kent, I'll try to get to it asap.

Awesome PR. Thanks @KentHsu

Can you run tox -e flake8 and tox -e ruff please?

The linter is failing at the moment.

That step runs tox -e flake8, tox -e type, tox -e mypy and tox -e ruff.

[elena-kolevska]

Great PR @KentHsu, thank you! I have just a few nits.

[elena-kolevska]

This PR should address the linter failing: #725

[berndverst]

@KentHsu we are beyond code freeze - are you able to address the comments from @elena-kolevska by end of next week? Otherwise, this is unfortunately going to miss the 1.14 release of the SDK.

[berndverst]

Currently seeing type check failures as well.

I recommend running the above mentioned commands to resolve type check, lint, autoformatting etc

[KentHsu]

Hi @berndverst, @elena-kolevska,
Thank you for reviewing this PR. I just added some commits to address @elena-kolevska's comments.

Really great work @KentHsu.
I'm approving the PR so as not to block the release, but to make this contribution 100% complete we would need a little example in the docs (this file) so that developers can discover and use your work.
It would be great if you could send a new PR with that addition.
Thanks again for your contribution, the community appreciates it!
