Python (aiogram): When clicking on an inline button, how to send the contents of the button to the bot?

Question

Python

There is a list:

l = ['Яблоко', 'Груша']
keyboard = types.InlineKeyboardMarkup()
backbutton = types.InlineKeyboardButton(text="Back", callback_data="MainMenu")
button_list = [types.InlineKeyboardButton(text=x, callback_data=x) for x in l]
keyboard.add(*button_list, backbutton

which gives values ​​from the list to separate inline buttons, the problem is that when you click on the button, this value is not transferred back to the bot ... I read all the documentation on inline buttons, about callback query, etc. ... still nothing happens when you click , can someone tell me, on the shelf t.s. decompose?
