How to include GoogleARCoreServices plugin

Hello,
I am trying to play around with the AR in UE4.19. I am wanting to try cloud anchors and mess with multiplayer options. I can see some documentation stating that I need to include the plugin for GoogleARCoreServices but I cannot figure out how to download it or what I need to do. Can someone please help me? I know I must be missing something obvious. I’ve downloaded the latest ARKit and that doesn’t help me either. Launching the example there states that the plugin is missing. The links in the following walk through for IOS did not work for me.
