Thank you for the contribution @zhengruifeng !

Oh, preview-docs is failing. Need to look into that separately.
I built the docs locally and the change renders correctly:

I do have one suggestion: as you have added examples with nulls, one of them could be selected to demonstrate the use of skip_nulls option. And similarly we could include the min_count option, maybe in form of ScalarAggregateOptions?

@AlenkaF thank you so much for the review and validation. I have updated the examples according to your suggestions, thanks!

@zhengruifeng the preview-docs job is not working at the moment. Will open a separate issue to tackle that.

Thank you for the updates, the examples look great!
Will build the docs locally one more time before merging.
