how can i log the auto_afk event?

[kfcisme]

I'm using below api to listen if the player is in afk or not,
but i notice that only using /afk command is worked
is there any other way to check if player is afk?
or im using the wrong way?
net.ess3.api.events.AfkStatusChangeEvent

the code to listen afk

public void onAfkStatusChange(LogPlayerAction_paper plugin) {
        Plugin essentials = plugin.getServer().getPluginManager().getPlugin("Essentials");
        try {
            Class<? extends Event> afkClass =
                    (Class<? extends Event>) Class.forName("net.ess3.api.events.AfkStatusChangeEvent",
                            true,
                            essentials.getClass().getClassLoader());
            Method getValue = afkClass.getMethod("getValue");
            Method getAffected = afkClass.getMethod("getAffected");

            PluginManager pm = Bukkit.getPluginManager();
            Listener dummyListener = new Listener() {};

            pm.registerEvent(
                    afkClass,
                    dummyListener,
                    EventPriority.MONITOR,
                    (listener, event) -> {
                        try {
                            Object affected = getAffected.invoke(event);
                            Method getBase = affected.getClass().getMethod("getBase");
                            Player player = (Player) getBase.invoke(affected);
                            UUID uuid = player.getUniqueId();

                            boolean isAfk = (boolean) getValue.invoke(event);

                            if (isAfk) {
                                afkStartTime.put(uuid, System.currentTimeMillis());
//                                plugin.getLogger().info(player + "is now AFK");
                            } else if (afkStartTime.containsKey(uuid)) {
//                                plugin.getLogger().info(player + "is no longer AFK");
                                long start = afkStartTime.remove(uuid);
                                int duration = (int) ((System.currentTimeMillis() - start) / 1000);
                                afkTotalSeconds.put(uuid, afkTotalSeconds.getOrDefault(uuid, 0) + duration);
                            }
                        } catch (Exception ex) {
                            plugin.getLogger().warning("AFK fail：" + ex.getMessage());
                        }
                    },
                    plugin,
                    true
            );

            plugin.getLogger().info("✔ successful register EssentialsX AFK event");

        } catch (ClassNotFoundException e) {
            plugin.getLogger().warning("❌ cant find EssentialsX AFK event class, skip the event registration.");
        } catch (Exception e) {
            plugin.getLogger().warning("❌ [ERROR] " + e.getMessage());
        }
    }
