(aiogram) How to disable access to the inline button to other users than the specified one?

Question

Python

I apologize in advance for the stupid question. See what the problem is: I am writing a "Russian Roulette" bot, after the command you need to put the nickname of your opponent, after which a message with two buttons is displayed in the chat. One "Accept", the other "Do not accept". It is necessary to make it so that when the button is pressed, the bot checks the ID and compares it with the specified one. The required line is:

from aiogram import Bot, types
from aiogram.dispatcher import Dispatcher
from aiogram.utils import executor

from config import TOKEN

bot = Bot(token=TOKEN)
dp = Dispatcher(bot)


@dp.message_handler(commands="ruletkaid")
async def inlinebtn(message: types.Message):
    user1 = str(message.get_args())
    user2 = str(message.from_user.username)
    return user1
    keyboard = types.InlineKeyboardMarkup()
    keyboard.add(types.InlineKeyboardButton(text="Принять", callback_data="random_value"))
    keyboard.add(types.InlineKeyboardButton(text="Не принимать", callback_data="da", ))
    await message.answer(user1 + ', вас вызывает на дуэль ' + user2, reply_markup=keyboard)


@dp.callback_query_handler(text="random_value")
async def send_random_value(call: types.CallbackQuery):
    global user1
    userid = call.message.from_user.username
    if userid != user1:
        await call.answer(text="Не тебе адресовано.", show_alert=True)
        return False
    await call.answer(text="Код сработал.", show_alert=True)


@dp.callback_query_handler(text="da")
async def send_random_value(call: types.CallbackQuery):
    await call.reply.edit(text="Вы не приняли предложение противника.")

Here. Hope you can help. Thanks in advance.

return user1
here it at all did not understand
Place username of users in callback_data. In the handler, get their username from data and compare it with the one who clicked the button.

@dp.message_handler(commands="ruletkaid")
async def inlinebtn(message: types.Message):
    user1 = message.get_args()
    user2 = message.from_user.username
    keyboard = types.InlineKeyboardMarkup()
    keyboard.add(types.InlineKeyboardButton(text="Принять", callback_data=f"accept_{user1}:{user2}"))
    keyboard.add(types.InlineKeyboardButton(text="Не принимать", callback_data=f"decline_{user1}:{user2}"))
    await message.answer(user1 + ', вас вызывает на дуэль ' + user2, reply_markup=keyboard)


@dp.callback_query_handler(lambda call: call.data.startswith('accept_'))
async def accept_duel(call: types.CallbackQuery):

    user1, user2 = call.data.replace('accept_', '', 1).split(':')

    if call.from_user.username != user1:
        await call.answer(text="Не тебе адресовано.", show_alert=True)

Haven't tested it, but it seems to work
