How do i add handler to InlineKeyboardButton, so i can use data from message ubove it?

Question

I gather data from Firebase Realtime Database and send it to Telegram bot as messages with buttons, that use varaiables from message used.

I want to catch the two variables longitude and latitude, then use it in the function lower, how can i do that?

@dp.message_handler(Text(equals='Get Maps'))
async def get_maps(message: types.Message):
    await message.answer('Please wait a bit...')


    data = collect_maps()

    keyboard = types.InlineKeyboardMarkup()

    key = types.InlineKeyboardButton('Get Location', callback_data='Get Location')
    keyboard.add(key)


    await message.answer('Your maps, that i collected:')
    for index, item in enumerate(data):
        card = f'{index+1}) {item.get("id")} - {item.get("name")}\n' \
            f'Longitude: {item.get("longitude")}\n' \
            f'Latitude: {item.get("latitude")}\n'

        await message.answer(card, reply_markup=keyboard)
