I have a 3D tikz diagram and I want to add some arrows to it.

I want the arrow to point to a specific coordinate in the 3D diagram, but I want the other end of the arrow to be aligned in the 2D plane of the page.

Sort of like this:

I am using tdplotsetmaincoords{}{} to set the rotation of the 3D diagram. I want the “2D coord” ends of the arrows to be unaffected if I change the rotation of the 3D diagram, but I want the “3D coord” ends of the arrows to rotate with the diagram.

Is there a way to do this? (without just using math)
