swift – How to get iOS LiveActivity to change status to timer completed

I’m using the timerInterval for the live activity however when the timer expires it doesn’t change its status to completed state and I couldn’t find a listener to call that

Text(timerInterval: Date()...context.state.endDate, countsDown: true, showsHours: false)

struct CompactTrailingView: View {
    let context: ActivityViewContext

    var body: some View {
        if context.hasExpired || context.state.isPaused {
            Text(context.formattedTime)
                .foregroundColor(.white)
                .font(.Widget.heading2Regular14.monospacedDigit())
                .monospacedDigit()
                .multilineTextAlignment(.center)
        } else {

            Text(timerInterval: Date()...context.state.endDate, countsDown: true, showsHours: false)
              .frame(maxWidth: .minimum(50, 50), alignment: .leading)
              .foregroundColor(.white)
              .font(.Widget.heading2Regular14)
              .monospacedDigit()
              .multilineTextAlignment(.center)
              .transaction { $0.animation = nil }
        }
    }
}
