如何在discord.py中使用按钮构造函数？

import discord
from discord_components import DiscordComponents, Button

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

@bot.command()
async def button_example(ctx):
    await ctx.send(
        "这是一个按钮示例",
        components=[
            Button(style=discord.ButtonStyle.primary, label="按钮1"),
            Button(style=discord.ButtonStyle.secondary, label="按钮2"),
            Button(style=discord.ButtonStyle.success, label="按钮3"),
            Button(style=discord.ButtonStyle.danger, label="按钮4"),
        ],
    )

@bot.event
async def on_button_click(res):
    if res.component.label == "按钮1":
        await res.respond(content="按钮1被点击了！")
    elif res.component.label == "按钮2":
        await res.respond(content="按钮2被点击了！")
    elif res.component.label == "按钮3":
        await res.respond(content="按钮3被点击了！")
    elif res.component.label == "按钮4":
        await res.respond(content="按钮4被点击了！")

pip install discord-components
