I've got error: `navigation destination com.example.app.myapp/action_homeFragment_to_mainFragment is unknown to this NavController`

```
mainFragmentViewModel.navigateToHome.observe(this, Observer {
            if (it) {
                this.findNavController().navigate(R.id.action_mainFragment_to_homeFragment)
            } else {
                this.findNavController().navigate(R.id.action_homeFragment_to_mainFragment)
            }
        })
```

You cannot access an action defined in HomeFragment tag of your Navigation graph in Main Fragment.
You should handle going to MainFragment from HomeFragment in Home Fragment.
