I want to find the closest path to the polyline

Question

I need your knowledge to make my application, thanks in advance. Well, I'm using Android Studio - Java - Using the Google maps API, I generated several polylines on the map, I also added my current position, what I need is to generate a route that will take me to the nearest polyline and referring to the first image, I have a polyline with a certain number of coordinates represented by the red dots. The light blue dot would be my current position. What I need is to find the closest path to the polyline without needing it to be one of the coordinates

(PS: I don't speak English if you can explain me in the simplest way possible)

I found some examples but they all seek to

find the closest coordinate of the red points but the truth is that I want the closest point to the polyline

, it is a challenge for me so I am looking for help.
