Can't get message from message response

Question

Pycord version: 2.0.0b4

I want to make a bot that sends a message, then adds two reactions to that message when the slash command is used. I tried to get the message and add a reaction but the line message = await ctx.channel.fetch_message(message.id) produces the error. How do I get the specific message to add the reaction in Pycord?

Code

  message = await ctx.respond(embed = embed_check)
  print(message.id)
  print(ctx.channel)
  global message_react
  message_react = await ctx.channel.fetch_message(message.id)
  print(message_react)
  message_react.add_reaction("✅")

I tried to get the message.id from the response, but it gives the following error:

Traceback (most recent call last):

import discord
import os
import random
import asyncio

testing_servers = [912361242985918464]
intents = discord.Intents().all()
bot = discord.Bot(intents=intents)

@bot.event
async def on_ready():
    print('Online!')

@bot.slash_command(guild_ids=testing_servers, name="announce", description="Make server announcements!")
async def announce(ctx,channel_id : discord.Option(str, description = "Copy the text channel in developer mode."),title:str,text : str):
    #response embed
  try:
    channel = bot.get_channel(int(channel_id))
  except ValueError:
    channel = channel_id
    #announcement embed
  embed_check = discord.Embed(
    colour = discord.Colour.blue(),
    title = "Is this embed shown correct?",
    description = title + "\n" * 2 + text
    
  )
  
  response = await ctx.respond(embed = embed_check)
  print(ctx.channel)
  global message_react
  message_react = await response.original_message()
  print(message_react)
  await message_react.add_reaction("✅")


  embed_announce = discord.Embed(
      colour = discord.Colour.blue(),
      title=str(title),
      description = text
  )
  await channel.send(embed = embed_announce)

  embed = discord.Embed(
      colour=discord.Colour.blue(),
      title = "Sent!",
      description= "Check the channel!"
  )

  await ctx.send(embed = embed)

This should do the trick. You should be aware that if you were to add a ctx.response.defer() this will no longer work, since ctx.respond returns a WebhookMessage instead of an Interaction, which you can't add emoji to.
