如何在嵌入式discord.py中使用markdown语法发送图像

import discord

client = discord.Client()

@client.event
async def on_ready():
    print('Bot is ready.')

@client.event
async def on_message(message):
    # 检查消息是否以特定指令开始
    if message.content.startswith('!send_image'):
        # 获取消息中的图片URL
        image_url = 'https://example.com/image.png'  # 图片的URL
        
        # 构建富文本消息
        embed = discord.Embed()
        embed.set_image(url=image_url)
        
        # 发送富文本消息到当前频道
        await message.channel.send(embed=embed)
