EyeGestures NOT working in 19.1

I built an app to recognize EyeGestures using https://github.com/thorikawa/EyeGestureLib and it was working great in XE18.3 But after the 19.1 update, I'm getting an error that certain virtual methods were unable to resolve. However, these methods DO exist in my class EyeGestureManager. Is this due to the update? Is there something I can do to fix this for XE19.1 or do I have to wait until GDK officially supports eye gestures?

EyeGestureLib accesses 'hidden' APIs which seem to have changed as of XE19.1: https://github.com/thorikawa/EyeGestureLib/issues/2

Unfortunately, it looks like you'll either need to wait until the library is updated or an official wink gesture library is released.
