The type or namespace name 'Analytics' does not exist in the namespace 'Unity.Services'

I just upgraded the IAP package, and now Unity no longer finds Analytics where it used to be. I can’t find any answers on this from googling. What is the correct way to use Analytics now? I’m still on the latest 3.6.12 in Unity 2021.3.16f1.
The documentation page for Analytics is full of 404’s.

I think I realized that this broke because there is a whole new analytics library, and apparently IAP no longer requires the old one to work, so I could remove it.
