dpymenus，discord.py如何在菜单中获取当前选定的页面

from discord.ext import commands
from discord.ui import View, Select, SelectOption

class MyMenu(View):
    def __init__(self):
        super().__init__()

        options = [
            SelectOption(label='Page 1', description='First page', value='page1'),
            SelectOption(label='Page 2', description='Second page', value='page2')
        ]

        self.add_item(Select(options=options, placeholder='Select a page'))

    async def interaction_check(self, interaction):
        # 可以在这里添加权限控制逻辑
        return True

    async def on_select(self, interaction, select):
        if select.values[0] == 'page1':
            await select.message.edit(content='This is page 1')
        elif select.values[0] == 'page2':
            await select.message.edit(content='This is page 2')

    async def on_timeout(self):
        await self.message.edit(content='Menu timed out.')

bot = commands.Bot(command_prefix='!')

@bot.command()
async def menu(ctx):
    menu = MyMenu()
    await menu.start(ctx)

bot.run('your_token')
