How to know which point that AI picked to move to? (A* Pathfinding)

Hi, I have used A* Pathfinding for a project (point graphs) I want to know which point that my AI are moving to because All the graph points are an empty GameObjects placed to their parent as a root.

I tried to access graph data scripts and I don't find the best way to detect the point that my AI chosen as his next path.

for example: Whenever the AI start to move the point he is moving to will be placed in some variable called (my next point)
