Non-Deprecated way to get Boundary edge geometry

I was looking through the developer documentation for using boundary data (https://developer.oculus.com/documentation/unity/unity-ovrboundary/) and I noticed that the method mentioned for getting the geometry of the boundary's edge is deprecated.

boundary.GetGeometry(OVRBoundary.BoundaryType.OuterBoundary)

Specifically, the BoundaryType.OuterBoundary enum is considered deprecated. I imagine this means there is a more updated way of getting this information but the page doesn't seem to mention it. Any assistance with this would be great!
