Error with data source

Hi,

i´m working with different data sources right now.
but i get an error with the data source “aws_organizations_organizational_unit”

 Error: Invalid data source

   on main.tf line 25, in data "aws_organizations_organizational_unit" "ou":
   25: data "aws_organizations_organizational_unit" "ou" {

 The provider hashicorp/aws does not support data source "aws_organizations_organizational_unit".

 Did you intend to use the managed resource type "aws_organizations_organizational_unit"? If so, declare this using a "resource" block instead of a "data" block.

it says, it is not supported but i have it form the documentation , here is the link:
Link to documentation

I can work with other data sources just fine.
what did i do wrong here?

Thank you!
