How to reference pathfinder script?

So I’m having a bit of a problem referencing the script. I have the pathfinding script attached to the object and I wanted to reference that script from another script so I can update some of the variables on that graph. Some reason I can’t get the “using” import so I’m unable to reference the script.

EDIT: so I made a new project and it somehow works for some reason. Anyway, I am now wondering this, is it AstarPath that I would be getting the component as to referencing the script?
