discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: add_reaction() missing 1 required positional argument: 'self'

Question

Basically, I'm trying to create a poll/vote command that allows you to add the reactions ":thumbsup:" for agree and ":thumbsdown:" for disagree. For example:

User: Am I male?

Reactions: :thumbsup:, :thumbsdown:

Meaning of Reactions: [yes:no]

This is my full code:

@client.command()
async def poll(ctx, *, message):
    await ctx.send(f"{message}")
    await Message.add_reaction(emoji=u"\U0001F44D")

Whenever I call the command, the message is sent but the reaction is not added. This error pops up instead

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: add_reaction() missing 1 required positional argument: 'self'

The full error is here:

Ignoring exception in on_command_error

    await discord.Message.add_reaction(emoji=u"\U0001F44D")
TypeError: add_reaction() missing 1 required positional argument: 'self'

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

The discord.py send() function returns a Message, so all you should have to do is set your send function to a variable.

@client.command()
async def poll(ctx, *, message):
    message = await ctx.send(message)
    await message.add_reaction(u"\U0001F44D")

You need an instance of a message not a class, store your message in a variable. In this case the variable is msg:

@client.command()
async def poll(ctx, *, message):
    msg = await ctx.send(f"{message}")
    await msg.add_reaction(emoji=u"\U0001F44D")
