Anim Graph "Look At" node -> How to tell it I have a different fwd Axis?

I see that there is a “Look At Axis” parameter, but changing that does not seem to do what I think it does.

In the video I show what I am experiencing, and change the axis. I can see that the blue line indicates the z axis of the bone, which is where the camera of this char faces (and i would like for that to be what is made to face the target vector.

Thank you for any and all help
