❔ NLua csharp hooks

Hi. Im using NLua to embed Lua in my project. Rn i can replace default print method to use hooked console. How i can do same but for require method? in example it dosen't works

var script = """

    require "chunk";

    testPrint("hello world")
    print('test');

    """;

var chunk = """
    function testPrint(arg)
        print(arg .. "hook 2");
    end
    """;


var luaEngine = new NLua.Lua(true);
luaEngine.State.Encoding = Encoding.UTF8;

luaEngine.RegisterFunction("print", PrintHook<object>);
luaEngine.RegisterFunction("require", RequireHook);

try
{
    var result = luaEngine.DoString(script, "Main.lua");
}
catch (Exception ex)
{
    Console.WriteLine(ex);
}

static void PrintHook<T>(T text)
{
    Console.WriteLine($"Hooked {text}");
}

LuaStatus RequireHook(string chunkName)
{
    try
    {
        Console.WriteLine($"Hooked {chunkName}");
        // not works
        //return luaEngine.State.LoadString(chunk);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex);
    }
    // fallback
    return LuaStatus.OK;
}

var script = """

    require "chunk";

    testPrint("hello world")
    print('test');

    """;

var chunk = """
    function testPrint(arg)
        print(arg .. "hook 2");
    end
    """;


var luaEngine = new NLua.Lua(true);
luaEngine.State.Encoding = Encoding.UTF8;

luaEngine.RegisterFunction("print", PrintHook<object>);
luaEngine.RegisterFunction("require", RequireHook);

try
{
    var result = luaEngine.DoString(script, "Main.lua");
}
catch (Exception ex)
{
    Console.WriteLine(ex);
}

static void PrintHook<T>(T text)
{
    Console.WriteLine($"Hooked {text}");
}

LuaStatus RequireHook(string chunkName)
{
    try
    {
        Console.WriteLine($"Hooked {chunkName}");
        // not works
        //return luaEngine.State.LoadString(chunk);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex);
    }
    // fallback
    return LuaStatus.OK;
}
