Localization System not showing up in package manager

Questions & Answers

I read about the Localization System here:
https://docs.unity3d.com/Packages/com.unity.localization@0.5/manual/Installation.html

It seems pretty cool and I want to check it out for some future project. However when looking at my Package Manager with preview packages enabled I do not see the Localization System:

Does anyone else have this issue? Is the System called differently? Am I doing something wrong?

I am using Unity 2019.3.0.f3. I have added the new Input System (also in preview) through the package manager. So I don’t think this is an issue with the pm… or is it?

There is a “Show preview packages” option in the Package Manager.
If it doesn’t show the preview packages, what does it do?
