“I am developing QML application using PySide6 that builds the best route between two points on a map using OpenStreetMap (OSM) tiles and works offline. I want to create a route similar to Google Maps, with a visual representation of the road from point A to point B. Is there a way to achieve this with offline OSM tiles?”

Seamless Offline Operation:

Expected the application to function completely offline, with no reliance on internet connectivity once the necessary map data is cached.
Accurate Route Calculation:

Hoped to achieve route calculations that are as accurate and efficient as those provided by online services like Google Maps.
Smooth and Clear Route Rendering:

Wanted to visually represent the calculated route on the map, making it easy for users to see the best path between two points.
