It’s a dream team: Live Activities and Shortcuts. Activity Composer brings the two together, allowing you to use Live Activities in whatever way is most useful to you. You can either configure them manually within the app or set them up using an automation in the Shortcuts app. The activity adapts to the situation on your screen: when time is running out, the icon appears; on the lock screen or in CarPlay, you can see everything.
