Move a player's arm with the mouse

Is it possible to link a character’s arm movements to the movement of the mouse, preferably toggled? Obviously within the constraints of the character’s arm reach and flexibility.

Thanks.

Next question? How?

I’m not looking for someone to do the work, just guide me in the right direction.

There’s a free asset (in the store) that does this for a character’s head. I would think that it would be usable for the arm as well. Sorry I forgot the name. I think it’s something obvious like “Head Animator”.

Good luck!
