How to pass data between Intent with NaviationUI Java Android Studio

Question

I'm trying to make a navigation using NavigationUI as in this tutorial video. Below is code for my activity:

BottomNavigationView bottomNavigationView = findViewById(R.id.bottomNavigationView);
NavHostFragment navHostFragment = (NavHostFragment) getSupportFragmentManager().findFragmentById(R.id.fragmentContainerView);
NavController navController = navHostFragment.getNavController();

AppBarConfiguration appBarConfiguration = new AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
    R.id.dashboardMerchant, R.id.listMenuMerchant, R.id.addMenuMerchant).build();

NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
NavigationUI.setupWithNavController(bottomNavigationView, navController);

My question is how to pass data from my activity to firstFragment or between framents. I already read this tutorial to pass bundle object, but I didn't know where to put the passing code in my activity or fragment.

Any idea how to do this?

Below is the XML file of my_navigation.xml
