Track path for GPS

Hello guys, I'm wondering how games make the path indicator on the minimap? Like Forza Horizon 5, for example.

I tried using NavMesh and LineRenderer on a track that I have, but the line doesn't keep on the middle of the track.

NavMesh.CalculatePath(player.position, destination.position, NavMesh.AllAreas, path); lineRenderer.SetPositions(path.corners);
