Попытка получить одного специального пользователя перед загрузкой любого другого обычного пользователя

Question

Я разрабатываю приложение чата на kotlin для Android. Я делаю это для своих клиентов, чтобы они могли поговорить со мной. Я пытаюсь реализовать 2 метода извлечения пользователей, один из которых будет использоваться для извлечения моей учетной записи, а другой - для извлечения других учетных записей. Второй метод работает нормально, но приложение не получает мою учетную запись. Я использую Firebase API для базы данных.

ПРИМЕЧАНИЕ. Методы используются в упражнении «Новое сообщение».
