Reaction Handling in Discord.py Rewrite Commands

Question

Is there a way to capture a reaction from a command. I have made a command that deletes a channel but I would like to ask the user if they are sure using reactions. I would

Here's a function I use for generating check functions for wait_for:

from collections.abc import Sequence

def make_sequence(seq):
    if seq is None:
        return ()
    if isinstance(seq, Sequence) and not isinstance(seq, str):
        return seq
    else:
        return (seq,)

def reaction_check(message=None, emoji=None, author=None, ignore_bot=True):
    message = make_sequence(message)
    message = tuple(m.id for m in message)
    emoji = make_sequence(emoji)
    author = make_sequence(author)
    def check(reaction, user):
        if ignore_bot and user.bot:
            return False
        if message and reaction.message.id not in message:
            return False
        if emoji and reaction.emoji not in emoji:
            return False
        if author and user not in author:
            return False
        return True
    return check

We can pass the message(s), user(s), and emoji(s) that we want to wait for, and it will automatically ignore everything else.

check = reaction_check(message=msg, author=ctx.author, emoji=(emoji1, emoji2))
try: 
    reaction, user = await self.client.wait_for('reaction_add', timeout=10.0, check=check)
    if reaction.emoji == emoji1:
        # emoji1 logic
    elif reaction.emoji == emoji2:
        # emoji2 logic
except TimeoutError:
    # timeout logic
