'Bot' object has no attribute '_bridge_commands'

[AnonymousHacker1279]

Summary

@bot.bridge_command() inside of a cog causes a crash.

Reproduction Steps

1. Make a bridge command inside of a cog
2. Enter bot token
3. Attempt to start bot
4. Bot fails to start

Minimal Reproducible Code

# main.py
import discord
from discord.ext import bridge, commands

from cogfile import SampleCog

intents = discord.Intents.all()
bridge_bot = bridge.Bot(command_prefix=commands.when_mentioned_or("!"), intents=intents)

bridge_bot.add_cog(SampleCog())
bridge_bot.run("token")

# cogfile.py

from discord.ext import commands
from discord.ext.bridge import bot


class SampleCog(commands.Cog):

	@bot.bridge_command()
	async def test(self, ctx):
		await ctx.respond("test")

Expected Results

The cog will be added, and the bot will start as in 2.3.0.

Actual Results

The bot crashes with an error and will not start.

The above exception was the direct cause of the following exception:
