class CPContactCallButtonOverview
Use this button to call the template’s contact.
If your app doesn’t provide VoIP functionality, use the tel URL scheme to start a phone call with the contact. Invoke your template application scene’s open(_:options:completionHandler:) method and pass the URL. CarPlay provides this scene to your CPTemplateApplicationSceneDelegate when the scene connects.
