Scenario { once user get logged In successfully I want to navigate user to -> graphB(Profile Page) but once user press back button he go back to Graph B (Home Fragment) }

Answer 1

In logged successfully response you redirect your fragment to profile page

            findNavController(R.id.nav_host_fragment).navigate(R.id.navigation_profile_page)

and on back button redirect the home fragment

            findNavController(R.id.nav_host_fragment).navigate(R.id.navigation_home)
