GPIO triggers for Discord.py bot messages

Question

TL;DR: I am trying to build a Discord bot to send a scripted message when physical buttons are pressed - returning error codes for sending message

I'm working on a Discord bot to send lab status to a specific channel for my club workshop. It was supposed to be a weekend project but we all know how that goes. I've gotten the beginning done with the buttons and such but am not sure how to trigger a bot command with the GPIO pins. Every setup that makes sense to me is given an issue due to my lack of understanding how to trigger a message on the computer side and not by !messages.

My code so far is here:

from os import system
from datetime import date
from time import sleep

from gpiozero import LED, Button
import discord
from discord.ext import commands

with open('token.txt', 'r') as f:
    TOKEN = f.read()
with open('channel.txt', 'r') as f:
    CHANNEL = f.read()
description = '''EVC Lab Bot'''
bot = commands.Bot(command_prefix='!', description=description)

client = discord.Client()

openbutton=Button(17)
pendingbutton=Button(27)
closedbutton=Button(22)

openlight=LED(4)
pendinglight=LED(23)
closedlight=LED(24)

openmessage=':green_circle: :radio_button: :radio_button: OPEN :green_circle: :radio_button: :radio_button:'
pendingmessage=':radio_button: :yellow_circle: :radio_button: PENDING :radio_button: :yellow_circle: :radio_button:'
closedmessage=':radio_button: :radio_button: :red_circle: CLOSED :radio_button: :radio_button: :red_circle:'

@client.event
async def msg(status):
    await ctrx.send('shit works')


def on_ready():
    print('on ready')
    while True:
        if openbutton.is_pressed:
            print('sizable green button')
            msg('open')
            openlight.on()
            pendinglight.off()
            closedlight.off()
            openbutton.wait_for_release()
            sleep(10)
        elif pendingbutton.is_pressed:
            print('Large Yellow Button')
            
            openlight.off()
            pendinglight.on()
            closedlight.off()
            pendingbutton.wait_for_release()
            sleep(10)
        elif closedbutton.is_pressed:
            print('BIG RED BUTTON')
            
            openlight.off()
            pendinglight.off()
            closedlight.on()
            closedlight.wait_for_release()
            sleep(10)

bot.run(TOKEN)
print('booting')
on_ready()
