How to fix a bug with issuing a role in a python discord bot?

Question

Python

There is a server and there when you write a command the role should be given.
Throws the error
discord.ext.commands.errors.MissingRequiredArgument: self is a required argument that is missing.

@bot.command()
async def PasL134(ctx, self):
    author = ctx.message.author
    guild = self.get_guild(тут айди сервера) 
    role = guild.get_role(тут айди роли)


    await author.add_roles(role)
    await message.channel.send(f"{author.mention}, пасхальная роль выдана!")

Answer 1

what else is self.get_guild(), and why can't you take guild from ctx?
Discord.py currently expects self to be passed as a parameter when the user invokes the command.
