Команда дерева 2 аргумента

Я видел ботов, таких как Dyno, которые могут иметь 2 аргумента в одной команде косой черты, я хотел бы сделать то же самое с командой косой черты DM, которая была бы примерно такой: /dm @user Привет!

Я попытался использовать этот код в discord.py:

@tree.command(guild=discord.Object(id=guild_id), name='userping', description='DM the user to come back to the ticket')
@app_commands.describe(user = "The user you want the DM to be sent to", reason = "The reason to ping this user")
@app_commands.default_permissions(manage_channels=True)
@app_commands.checks.cooldown(3, 20, key=lambda i: (i.guild_id, i.user.id))
@app_commands.checks.bot_has_permissions(manage_channels=True)
async def userping(interaction: discord.Interaction, reason: str, user = discord.Member):
    if "ticket-for-" in interaction.channel.name:
        l=1
    else:
        await interaction.response.send_message("This isn't a ticket!", ephemeral=True)

Он возвращает:

Traceback (most recent call last):
