我有一个discord.py2.0按钮组件，我需要确保单击按钮的人是发起提示的人。但我不知道如何获得单击按钮的人，以便我可以比较它太ctx.author。以下是我到目前为止所做的。

@bot.command()
async def prompt(ctx):
    positive = Button(label="Yes", style=discord.ButtonStyle.green)
    negative = Button(label="No", style=discord.ButtonStyle.red)

    async def positive_callback(interaction):
        if ctx.button == ctx.author:  # ctx.button is not a real argument, that is what needs to be the user who clicks the button.
            await interaction.response.edit_message(content=f"{ctx.author.mention} Here is some cake ❤", view=None)

    positive.callback = positive_callback

    view = View()
    view.add_item(positive)
    view.add_item(negative)
    await ctx.send(content=f"{ctx.author.mention} Would you like to have some cake?", view=view)
