Why does on_member_join() is not working in my discord.py bot? [duplicate]

Question

I try to run this code below, but on_member_join is not working for me.

    async def on_member_join(self, member):
        guild = member.guild
        if guild.system_channel is not None:
            to_send = f'Welcome {member.mention} to {guild.name}!'
            await guild.system_channel.send(to_send)
            # self.logger.info(f'{member.mention} 加入了伺服器')

full code: https://github.com/Cutespirit-Team/CutespiritDiscordBot/blob/main/src/ctbot/ctbot.py#L66-L71

run python -m src/ctbot/

I have already turned this on.

when a user enter my server, it will show the default message. how can i fix it? thx

Make sure to subscribe to members intent.

class Bot(commands.Bot):
    def __init__(self):
        intents = discord.Intents.default()
        intents.members = True
        super().__init__(intents=intents)

I used this but Im new to this stuff so idk its better or worse just know it works for me:

async def on_member_join(member):
    channel = bot.get_channel(channel_id)
    embed=discord.Embed(title='Welcome!', description=f"{member.mention} Just Joined")
    await channel.send(embed=embed)
