Localization

I found official description about Unity Localization here:
https://docs.unity3d.com/Packages/com.unity.localization@0.4/manual/

But I can't find it's package in Package Manager in Unity 2019.2. `Show preview packages` selected of course. And ideas where I can download it?

 

Found that it required to modify manifest to install:
