Transferring a participant to another channel, how to do it via @bot.event?

Question

Python

My code:

@bot.event
async def on_message(message):
    guild = bot.get_guild(699607137227243550)
    channel = discord.utils.get(guild.voice_channels, id=785085589305294868)
    await bot.process_commands(member)
    if message.content.startswith(f'!move {member.mention}'):
        await member.move_to(channel)
