You can pass any of the tokens to the SwiftUI Label constructor to show the app name and/or icon.

The tokens conform to Codable, so you can use standard Codable functionality to read and write an encrypted representation of the tokens. To show the text and/or icon for a token, you can pass it to a Label view in SwiftUI.

Are there any errors coming from the startMonitoring() call? There are limits on how short a time interval can be for a DeviceActivitySchedule; the minimum is 15 minutes, and the maximum is a week. If you're doing a two minute interval, you should be getting an intervalTooShort error. For my own app, when I want to unblock an app for a period of time, I use an interval that starts at the time the shield should be re-applied and ends when the primary schedule ends (or some time later, if that would be too short). Then I re-apply the shield on the intervalDidStart event.
