How to hide the react-datepicker header?

I’m trying to hide the header in the react-datepicker. And from what I read it should just be the tag hideHeader. but it does not seem to be working for me.

according to this, the feature was added in 2017
https://github.com/Hacker0x01/react-datepicker/pull/1026

But when I read their documentation hideHeader is not listed
https://github.com/Hacker0x01/react-datepicker/blob/main/docs/datepicker.md

Here is my code:

<DatePicker  ...
             showMonthDropdown={true}
             showYearDropdown={true}
             hideHeader />

Did they remove this feature? or am I adding it in wrong? I also tried hideHeader={true} but it does not seem to work.
