Describe the question
I want to do code when player open inventory with E button.

API method(s) used
Using maven.

Expected behavior
I want to do code when player open inventory with E button.

Code

    public testClick() {
        ProtocolManager manager = ProtocolLibrary.getProtocolManager();
        manager.addPacketListener(new PacketAdapter(MCPPlayer.getPlugin(), ListenerPriority.NORMAL, PacketType.Play.Client.CLIENT_COMMAND) {
            @Override
            public void onPacketReceiving(PacketEvent e) {
                Player player = e.getPlayer();
                PacketContainer packet = e.getPacket();
                EnumWrappers.ClientCommand action = packet.getClientCommands().read(0);
                if (action == EnumWrappers.ClientCommand.OPEN_INVENTORY_ACHIEVEMENT) {
                    player.sendMessage("ta");
                }
            }
        });
    }

Additional context
I read on spigot forum that Client_command packet can read when player open his inventory with E button. Other packet like CHAT works correctly, but when i want to fire code after Client_Command packet code doesn't work.

CLIENT_COMMAND is not the correct packet, you're listening to opening the stats menu. There is no packet send to the server when opening the local player inventory.

then which packet are fired when player open his inventory? i see that server do that when player open his workbench was filled with items
