How to display aiogram notification?

Question

Python

Hai, I want to display a sneaky notification when the button is clicked:


Code:

@dp.callback_query_handler(lambda call: True)
async def callback_inline(call):
    await call.answer()
    id_user = call.from_user.id
    if 'pchanel_' in call.data:
         await call.answer('test', show_alert=False)
         print('test')

In this way, it does not display a notification and there are no errors, while the print works

Handler doesn’t work for you, you
should use lambda differently
, for example, you have a button:

btn = InlineKeyboardButton(text="Яблоко", callback_data='button228')

next we write handler:

@dp.callback_query_handler(lambda c: c.data == 'button228') 
async def apple_test(call: CallbackQuery):
    await call.answer(text='Яблоко взято')
