Need Help in coverting a mapbox function

Nobody has claimed this yet.

We are converting our app from 10.0.rc6 to 10.18 and seem to be stuck on a conversion.

What is the equivalent of this function I cannot find any documentation on using this with the newer versions of Turf

let point = annotations.feature.geometry.value as! Turf.Point

Geometry no longer has the value enum

We can't convert to version 11 because it breaks our custom polygon dragging. 10.18 seemed like a possible compromise but we ran into this issue among others, it would be great to have some conversion guide or at least update examples like the MultipointAnnotation example between versions,

Start by comparing the Geometry API between 10.0.rc6 and 10.18, focusing on the Turf.Point cast shown in the issue. Review the MultipointAnnotation example and determine what migration guidance or example updates are needed for users who cannot move to version 11. Done means the 10.18 conversion path is documented clearly, including the replacement for Geometry.value.
