Adding new point to a point graph using GraphUpdateObject is not work

Beginner Questions
1

In runtime, I want to add a new point to an existing point graph using GraphUpdateObject with a bound area, but the new point do not connected to the graph. Or I need to do it manually ?

Point Graph only have support for updating penalty, walkability and similar on already existing nodes using GraphUpdateObject?

Hi

Point graphs need to be rescanned if you have added a new point.
AstarPath.active.Scan()
Will recalculate the graph.

Is it possible to recalculate only a region of points like grid graph ?
