Hello, Welcome to Micorosoft Q&A,
Customizing PaneToggleButton Icon and Position in NavigationView UWP
if you has checked NavigationView style. you will find TogglePaneButton was placed on the RootGrid and on the top level, but not on the pane, so you can't place it on the right of panel.
For above design, the better way is make navigation base on SplitView. And make arrow button to control the splitview open or not.
