问如何将commands.Bot()中的内置帮助命令模拟为bot.tree？

EN

class MyHelp(commands.HelpCommand): 

    async def send_bot_help(self, mapping):
        if self.context.guild.id != master_guild:
          return
        names = [command.name for command in bot.tree.get_commands()] # iterating through the commands objects getting names
        available_commands = "\n".join(names) # joining the list of names by a new line
        embed  = discord.Embed(title=f"Commands ({len(names)}):",description=available_commands)
        embed.set_footer(text=f"  {prefix}help <command> (e.g {prefix}help {random.choice(names)})")
        await self.context.send(embed=embed)

    async def send_command_help(self, command): # I am in the process of making this work for slash commands
        if self.context.guild.id != master_guild:
          return
        if len(command.description) == 0:  
          desc = "No description provided"
        else:
          desc = command.description
        e = discord.Embed(title=command.name,description=desc)
        e.set_footer(text="Usage: "+command.usage)
        await self.context.send(embed=e)

bot = commands.Bot(command_prefix=prefix, intents=discord.Intents.all(), help_command=MyHelp()) #help_command obviously not needed

@bot.event
async def on_ready():
        try:
          synced = await bot.tree.sync()
          print(f"Synced {len(synced)} command{'s' if len(synced) > 1 else ''}.")
        except Exception as e:
          print(f"Error syncing commands: {e}")


@bot.tree.command(description = "Sends help")
@app_commands.describe(command = "Enter command")
async def help(ctx: discord.Interaction, command:str=None):
  await ctx.channel.send_help(ctx.command)
