Hello what changes (bytes and more) need to use store shop in C++?

My is debbuging, code:

void ProtocolGame::sendCoinBalance()
{
    NetworkMessage msg;
    msg.addByte(0xF2);
    msg.addByte(0x01);

    msg.addByte(0xDF);
    msg.addByte(0x01);

    msg.add<uint32_t>(player->coinBalance); //total coins
    msg.add<uint32_t>(player->coinBalance); //transferable coins

    writeToOutputBuffer(msg);
}

void ProtocolGame::updateCoinBalance()
{
    NetworkMessage msg;
    msg.addByte(0xF2);
    msg.addByte(0x00);

    writeToOutputBuffer(msg);

    g_dispatcher.addTask(
        createTask(std::bind([](ProtocolGame_ptr client) {
            auto coinBalance = IOAccount::getCoinBalance(client->player->getAccount());
            client->player->coinBalance = coinBalance;

            client->sendCoinBalance();
        }, getThis()))
    );
}

void ProtocolGame::sendStore()
{
    NetworkMessage msg;
    msg.addByte(0xFB);

    msg.addByte(0x00);
    //msg.add<uint32_t>(player->coinBalance);
    //msg.add<uint32_t>(player->coinBalance);

    msg.add<uint16_t>(g_store->getCategories().size());
    for (auto& category : g_store->getCategories()) {
        msg.addString(category.getName());
        msg.addString(category.getDescription());

        msg.addByte(category.getIcons().size());
        for (const auto& icon : category.getIcons()) {
            msg.addString(icon);
        }

        msg.addString(category.getParent());
    }   

    writeToOutputBuffer(msg);   

    updateCoinBalance();
}

    }
