Hello, im using navigation button in action bar with text="Go Back" (for example). When i am routing to page(component) first time navigation button always show default text "Back" and then i go to the next page and then return, navigation button text shows "Go Back". How to fix this bug ? or should i just use custom ActionItem ?
p.s I am using different language for navigation button text
