In the docs in https://doc-snapshots.qt.io/neptune3ui-dev/neptune3ui-requests.html it is said:
In the energy panel is a list with 'charging station' suggestions. If any of those is pressed, the maps application will directly open, loading the selected charging station's address and ready to navigate there.
When tested on desktop on the released 5.13.1, the button "Show on map" can be pressed but seems to be non-functional. This is confusing. The both "Route" buttons open the Map app with the correct addresses, but there is no UI to start navigation as the docs say. Something is wrong here
