 - mode: Indicates the current phase of the Pomodoro session ("Work", "ShortBreak", "LongBreak", or "none" if no session is running).
 - session: The current session number (e.g., 1 for the first work session).
-- max_session: The total number of sessions for the current Pomodoro cycle (e.g., 4 if the cycle consists of 4 work/break sessions).
+- total_sessions: The total number of sessions for the current Pomodoro cycle (e.g., 4 if the cycle consists of 4 work/break sessions).
 - time_left: The remaining time for the current mode, in seconds (e.g., 900 for 15 minutes).
