Why is the unbanned command not working?

Question

Python

@bot.command() 
@commands.has_permissions(administrator=True)
async def unban(ctx, member:discord.Member, *reason):
    channel = bot.get_channel(894969274966368288)
    embed = discord.Embed( color=0xff0000, title='unban')
    embed.add_field(name='Модератор', value=ctx.message.author.mention)
    embed.add_field(name='Пользователь', value=member.mention)
    embed.add_field(name='Причина', value=' '. join(reason))
    await member.unban()
    await ctx.send(embed=embed)
    await channel.send(embed=embed)

I write a command and the bot does not respond

There is an assumption that the bot simply does not see the member, because it is not in the guild.
As I suggest. By ID, get not a member, but a user, and unban. Like this

async def unban(ctx, ID, *reason):
    user = await bot.fetch_user(ID)
    await ctx.guild.unban(user)
