请问如何拆分`export const registerIpcMainHandlers = () => {...}`里面的方法呢？

// subHandlers/handler1.ts
import { ipcMain } from 'electron';

export const handleMessage1 = () => {
  ipcMain.on('message1', (event, data) => {
    console.log(`Message received from ${event.sender.id}: ${data}`);
    event.sender.send('response', 'Response message from main process.');
  });
};

export const handleMessage2 = () => {
  ipcMain.on('message2', (event, data) => {
    console.log(`Message received from ${event.sender.id}: ${data}`);
    event.sender.send('response', 'Response message from main process.');
  });
};

// mainHandler.ts
import { handleMessage1, handleMessage2 } from './subHandlers/handler1';

export const registerIpcMainHandlers = () => {
  handleMessage1();
  handleMessage2();
  // ...
};
