Location: A-CHA only asks for "While Using the App" permission. Background location runs only after a user taps "Share live location" in a group chat and picks how long to share. People on a group tour use it to find the guide and each other. iOS shows the blue location indicator the whole time, and sharing ends when the time is up or the user stops it.
