I can't get a response from the server

Hi. The problem is this. The server sends a response. But I don’t understand how to accept it in c++. Can you tell me how to do this?
Code for sending the message to the server. What do I need to add to get a response from the server?

#include "TCPSocketFunction.h"
#include "Networking.h"
#include "Sockets.h"
#include "SocketTypes.h"
#include "SocketSubsystem.h"
#include <Engine.h>

bool UTCPSocketFunction::SendMessage(const FString Message) 
    FSocket* Socket = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateSocket(NAME_Stream, TEXT("TCP_TEST"), false);
    FString address = TEXT("");

    FIPv4Address ip;
    FIPv4Address::Parse(address, ip);

    TSharedRef<FInternetAddr> addr = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateInternetAddr();

    bool connected = Socket->Connect(*addr);

    if (connected)
        FString serialized = Message;
        TCHAR* serialuzedChar = serialized.GetCharArray().GetData();
        int32 size = FCString::Strlen(serialuzedChar);
        int32 sent = 0;
        bool successful = Socket->Send((uint8*)TCHAR_TO_UTF8(serialuzedChar), size, sent);
        if (successful)
            return true;
        return false;
    return false;
