Skeleton bone + AnimationTree Blending from mouse position

Godot Version

4.3

Question

Is it possible to animate a bone by using animationTree blending from mouse position? I have a mouse position projected onto the screen and I want that mouse position to dictate my animationTree blending relative to my Character position.

For example, Imagine this (at bottom screen)…

…But have my character at the center and the mouse position will blend the animation, in real game time.

ps. My camera3D will only project FORWARD.

Thanks
