Can someone brief me when should we use

requireActivity().findNavController(<xml>).navigate(<direction>)

vs simple

findNavController.navigate(<direction>)

? I've a common Fragment which I'm using in a main nav graph as well as inside a subgraph of

BottomNavigationBar

one of the tabs. In both the cases, this Fragment should launch a Fragment hosting this

BottomNavigationBar

(say Dashboard Fragment) so I created a self navigation for DashboardFragment and there exist one from main nav graph as well and I use either of them as per some condition to determining whether this child Fragment is being hosted inside a tab or as a dedicated screen (belonging to main nav graph)
