iOS 14 introduced EV routing in the Maps app as seen in the keynote. I maintain an EV app that currently conforms to INGetCarPowerLevelStatusIntent to provide updates via Siri about car power levels, charging and range. iOS 14 introduced a lot of new methods including things like chargingFormulaArguments all of which have no documentation. I'm unable to get the maps app to suggest EV charge points when plotting routes (I'm using the example they showed in the keynote plotting a long route through California). It also introduces INListCarsIntent which I assume is supposed to be called by maps to figure out what vehicles the user might use for a journey. Again, I've implemented all the methods I can find and it's never triggered when using Maps. Is it simply the case that this functionality just flat out isn't enabled yet and doesn't work or am I doing something wrong? The complete lack of documentation is making it very hard to guess how to use these and I'd really love to get it all functioning ready for the launch of iOS 14. Any help/documentation/guidance massively appreciated here.
