How to display an error through the bot if the user did not enter one of the arguments?

Question

Python

I have two arguments in command arg1 and arg2.
How to make it so that an error is displayed (in a video message) to the user if he did not enter / skipped one / all arguments?

class MyBot(commands.Bot):
    async def on_command_error(self, ctx, e):
        if isinstance(e, commands.MissingRequiredArgument):
            await ctx.send(f"Недостаточно аргументов: {e.param} отсутствует")
        else:
            super().on_command_error(ctx, e)  # вызвываем оригинальный обработчик ошибок команд
