Как поставить переключатель меню на правой стороне панели действий Android Studio

Question

У меня есть ящик для навигаторов, который отлично работает, но значок ящика находится на левой стороне панели действий, и я хочу, чтобы он был на правой стороне.

Я посмотрел еще один вопрос, опубликованный здесь, но не совсем понял, как применить его к моей проблеме

Значок переключения ящика навигации Android вправо

Кто-нибудь может помочь? Я прочитал форумы и другие вопросы, я не хочу, чтобы перевернуть макет

Вот план действий
