The material guidelines say to use a Navigation drawer when you have over 5 main menu items (as opposed to tabs or bottom navigation bar). https://material.io/guidelines/patterns/navigation.html
All examples I've seen have the navigation draw activated from a burger menu on the left side of the top toolbar. Example image...
My issue is that in an app that has a multi-level hierarchy, the burger in that location switches to a back arrow. Is there somewhere else the button should go to make it available on all pages?
I have also seen the kabab menu on the right side of the top toolbar, however this seems to be used more for a contextual menu (actions for the current screen), and not global items?
