how to convert this script to run multiple bots

I have a scripts which responsible for forwarding messages from one channel to other channels. Scripts looks something like below: How can I achieve to run different client on every channel. I am using Telethon.

client = TelegramClient('bot', api_id, api_hash).start(bot_token=bot_token)
client.start()

@client.on(events.NewMessage(chats=[channel_id]))
async def handler(event):
    channels = get_channels()
    replacements = get_replacements()
    msg_first = copy.copy(event.message.text)
    for channel in channels:
        replacements_api = get_replacement(channel['channel_id'], replacements)
        for rep_api in replacements_api:
            # do some stuff here

        await client.send_message(channel['channel_id'], message=event.message)
       
client.run_until_disconnected()
