How to handle inline keyboard inside state aiogram?

Question

Telegram

I want to process an inline keyboard, with a button to exit the current state to the main menu.
I usually use this syntax

@dp.callback_query_handler()
async def имя(callback_query: types.CallbackQuery):

For handling states

async def имя(message: types.Message, state: FSMContext):
    ...
dp.register_message_handler(имя, state=состояние)

The problem is that, firstly, simply processing the inline keyboard as usual does not work, while the Dispatcher is in a state, it does not call the handler at all

async def cancel(callback_query: types.CallbackQuery):
    ...
dp.register_callback_query_handler(cancel)

Secondly, I don’t know how then to get the state in order to call the finish () method on it.
I would be very grateful for any help!
