Как я могу добавить данные пользователю в базе данных реального времени firebase?

Question

Я пытаюсь добавить оценку пользователей к их узлу в базе данных Firebase в реальном времени, но оценка сохраняется отдельно, а не как часть текущей ветви пользователей. Я приложил код java для игры, в которой рассчитывается счет, вместе с кодом для класса входа в систему.

Я новичок в программировании и немного запутался, поэтому любая помощь приветствуется

Спасибо
