Check if user react with an certian emoji with cogs

I have a problem. How can I check which emoji the user reacted with? That did not work for me How do you check if a specific user reacts to a specific message [discord.py]

I want to check if the reaction is ✅ or ❌

folder structure

├── main.py
├── cogs
│   ├── member.py

The problem is that I don't get an error message. Nothing happens. As soon as I react with an emoji, nothing happens.

    def __init__(self, bot):
        self.bot = bot

                 ...
                    for emoji in emojis:
                        await msg.add_reaction(emoji)



                    await message.author.send('Send me that ✅ reaction, mate')

                    def check(reaction, user):
                        return user == message.author and str(reaction.emoji) == '✅'

                    res = await self.bot.wait_for(
                        "reaction_add",
                        check=check, timeout=None
                    )
                    print(res.emoji)

                    if res.content.lower() == "✅":
                        await message.author.send("Got it")
                    else:
                        await message.author.send("Thanks")
