Hello @arizeosalac!
Thanks a lot for the contribution. To me, it looks like being ready to merge, but would be nice to see that CI is happy. Could you please update your branch to accommodate the latest changes from main? The have been some recent environment fixes which make CI up and running again.

As a little comment, it appears from our discussion with @doneachh the changes you introduce are important to make work example notebooks. This PR should fix these troubles! 😄

@arizeosalac sorry, there is one more point: may you be willing to add a release note? 🙂
That is quite a substantial contribution, and I think it's worth to be mentioned in the release notes 😄
