I need to start my non-changing live activity at specific time e.g. after 5 mins or 1 hour. There are two way I can start at later date:

1. Using Local notification, but I will need the user to interact with
   it for it to actually call a method which starts the activity. May be user doesn’t seen that local notification and I will not get chance to start activity by calling a method.
2. Using push notifications, we can start live activity. But my live activity doesn’t update once I start it. Here is why:

I am using System UI component ProgressView that support auto-updating a live activity. So once I start live activity, the progress bas updated automatically every second, and that’s why I don’t need a push notifications to update my activity.

struct ParkWidgetAttributes: ActivityAttributes {
    
    var startDate: Date
    var endDate: Date

    // 'ContentState' represents the dynamic content of the Live Activity.
    public struct ContentState: Codable, Hashable {
        // Dynamic stateful properties about your activity go here!
        var parkingTimer: ClosedRange<Date>
    }
}

Here is how activity is updated:

ProgressView(timerInterval: context.state.parkingTimer,
                             countsDown: false)
                    .padding(.horizontal, 3)
                    .padding(.bottom, 5)
                    .tint(.fastParkTint)

The reason why I do not want to use push notifications is my activity doesn’t updates once it is started. Is there some other way, or I will have to use push notifications?
