APEX plugin for Maya

I have spent almost the entire day trying to navigate the Nvidia site for the Apex plugin for Maya 2016, but can’t seem to find it. The only thing I was able to find was the SDK (which didn’t come with a plugin). I also downloaded the PhysX for Maya 2016 but it didn’t seem to work (I didn’t any new tabs or buttons added into Maya). Tried installing it both while still running Maya and while it was closed.
