FIshing Pole

Im trying to create a fishing pole and am struggling with creating the reeling in of the lure. I instantiate a lure like a projectile during casting. That has a line renderer that draws a line from the lure to the tip of the rod to mimic the fishing line.

I would like to now reel in the lure by holding down a button.

I don't know how to go about having the lure get reeled in to the pole acting as if it were attached to that fishing line.

One idea I had was to use a hing joint and just shorten the distance values, but I fall short of doing so.

Is there any help out there that could help me do this?
