TFS 1.X+ Nekiro 7.72 downgrade | Modal window issue

[Rondel]

Hey, I've tried implementing modal window but I've encountered an issue - the modal window shows, however I don't get response when I click the buttons. I'm using OTCv8 and downgraded 7.72 TFS by Nekiro. I've followed the TFS 1.X+ - ModalWindow not executing functions (https://otland.net/threads/modalwindow-not-executing-functions.280727/) thread and uncommented the Game:layerAnswerModalWindow function in game.cpp aswell as ProtocolGame:arseModalWindowAnswer function in protocolgame.cpp. Perhaps all of this wasn't needed and the implementation is wrong . I tried implementing it that way:

local action = Action()
function action.onUse(player, item, fromPos, target, toPos, isHotkey)
  player:registerEvent("ModalWindowTest")
  local title = "Anti-mistake prompt"
  local message = "Are you sure that you want to use the teleportation scroll?"
  local window = ModalWindow(1111, title, message)
  window:addButton(100, "Yes")
  window:addButton(101, "No")
  window:setDefaultEnterButton(100)
  window:getDefaultEscapeButton(101)
  window:sendToPlayer(player)
  return true
end
action:id(1949)
action:register()
local creatureEvent = CreatureEvent("ModalWindowTest")
function creatureEvent.onModalWindow(player, modalWindowId, buttonId, choiceId)
  
  if modalWindowId == 1111 then
    if buttonId == 100 then
      print("yes")
    end
  end
  
  player:unregisterEvent("ModalWindowTest")
  return true
end
creatureEvent:register()
