In the new CarPlay Parking app category under iOS 14, is it possible to show a spinner when using CPPointOfInterestTemplate and the user changed map region? The reason why we would need this is that we query our servers for parking locations when the user changes map region. There are simply too many possible results for all of them to be loaded onto the device before opening CPPointOfInterestTemplate.

Is it possible to show a UIActivityIndicatorView or other loader class in a CarPlay Parking app? I saw that one doesn't have access to the CPWindow in a Parking app -- only in navigation apps. So there doesn't seem to be a way to attach a subView to something. I also went through the CPTemplates that are available to Parking apps searching for functions that might suggest that they would display a loader but couldn't find anything. In the interface guidelines it mentions - https://developer.apple.com/design/human-interface-guidelines/carplay/system-elements/activity-indicators/ showing loaders in CarPlay apps. So I'm thinking there must be a way to do so. Unless this human interface guideline page only applies to navigation apps only.
