Hey! thanks for opening this PR!

We have some problem with the CI/CD. Going to handle it soon and let this PR in :)

[shahargl]

@Nctllnty tests failing (see UT's, docs, examples, etc) - do you want to solve it?

[Nctllnty]

Hi @shahargl, I've fixed the linting errors and added the required docs, examples, and tests. The CI checks should be green now. Ready for re-review!
