Computing Shortest Path Distance for multiple points in QGIS

Question

I have been looking for ways on how to compute the shortest distance between one point to multiple points using a specific road network.

I have not been successful in achieving the solutions in this site.

Here's my case:

I have 3 shapefiles: 1. Road Network (lines) 2. Polygon Centroids 3. Source Point (Starting Point)

How do i easily compute the shortest distance between the starting point to the polygon centroids over the road network?

I am doing a similar analysis and using the plugin QNEAT3 https://root676.github.io/ShortestPathAlgs.html. it works very well for the purpose. // Frida
