Как поймать данные которые добавляются в файл?

имеется парсер при первом запуске он собирает полный список информации и сохраняет её в json файл. В дальнейшем ставлю на повтор выполнения цикла для обновления информации и добавления разницы в словар.После того как он добавляет информацию отправляю уведомление в телеграм. Но бот отправляет всю информацию из файла, отсюда вытекает вопрос как сделать что бы он отправлял только ту информацию которой ещё не было, а не все блоки? Заранее спасибо за помощь. Код парсера:

soup = bs(page, 'lxml')
    applications_cards = soup.find_all(class_=re.compile("OrderSnippetContainerStyles__Container"))
    with open ("new_applications.json") as file:
        new_applications = json.load(file)
    fresh_applications = {}
    for application in applications_cards:
        try:
            application_title = application.find('h3', class_=re.compile("SubjectAndPriceStyles")).text.strip()
        except Exception:
            application_title = "Нет заголовка"
        try:
            application_snippet = application.find('p', class_=re.compile("SnippetBodyStyles__MainInfo")).text.strip().replace('\n', ' ')
        except Exception:
            application_snippet = "Нет описания"
        try:
            application_location = application.find('span', class_=re.compile("LocationAndScheduleStyles__TextContainer")).text.strip()
        except Exception:
            application_location = "Адрес не указан"
        try:
            application_shedule = application.find('span', class_=re.compile("LocationAndScheduleStyles__ScheduleText")).text.strip().replace('\n', ' ')
        except Exception:
                application_shedule= "Дата не указана"    
            
        application_name_client = application.find('span', class_=re.compile("StatusAndClientInfoStyles__Name")).text.strip()
        application_link_req = application.find('a', class_=re.compile("SnippetBodyStyles__Container"))
        application_link = application_link_req.get('href')
        application_id = application_link_req.get('id')
        new_applications [application_id] = {
            "application_title":application_title,
            "desc":application_snippet,
            "location":application_location,
            "time_application":application_shedule,

            "application_id":application_id

        }
        with open ("new_applications.json", "w") as file:
            json.dump(new_applications, file, indent =4, ensure_ascii=False)
