ARkit Standalone Face Tracking with Metahumans

I was wondering if there are any good resources on packaging an Iphone App with working Face tracking using a metahuman? The old Face AR sample is from 4.27. And the documentation goes over how to play in editor, which I can connect to livelink just fine but I am looking for a way to get a Standalone app to register a metahuman face. Thoughts or suggestions?
