This must refer to a SphereCollider on the same slot as the SnapTarget. Usually refers to the one generated automatically when the SnapTarget was added.
Behavior
Allows the slot containing this component to receive slots that contain a Snapper component, the Snapper slot will enter the hierarchy of the SnapTarget slot and get positioned to the center.

SnapperKeywordWhitelist

Unlike grabbers, Snappers do not have a way to detect events directly. (GH#2059)
A common approach to drive something else to use ProtoFlux:ChildrenCount on the slot that contains a SnapTarget and monitor if it changes using ProtoFlux:Equals.
