```tsx
import { Transfer } from 'antd';
import type { TransferDirection } from 'antd/es/transfer';
import React, { useEffect, useState } from 'react';

interface RecordType {
  key: string;
  title: string;
  description: string;
  chosen: boolean;
}

const App: React.FC = () => {

  const getMock = () => {
    const tempTargetKeys = [];
    const tempMockData = [];
    for (let i = 0; i < 20; i++) {
      const data = {
        key: i.toString(),
        title: `content${i + 1}`,
        description: `description of content${i + 1}`,
        chosen: Math.random() * 2 > 1,
      };
      if (data.chosen) {
        tempTargetKeys.push(data.key);
      }

  useEffect(() => {

  }, []);

  const filterOption = (inputValue: string, option: RecordType) =>
    option.description.indexOf(inputValue) > -1;

  const handleChange = (newTargetKeys: string[]) => {
