Implementation change of fragment new instance
Suggestion is:
in ExplorationActivityPresenter

   if (getExplorationManagerFragment() == null) {
      activity.supportFragmentManager.beginTransaction().add(
        R.id.exploration_fragment_placeholder,
        ExplorationManagerFragment.newInstance(internalProfileId),
        ExplorationManagerFragment.TAG
      ).commitNow()
    }

In ExplorationManagerFragment

  companion object {
    internal const val EXPLORATION_MANAGER_FRAGMENT_INTERNAL_PROFILE_ID_ARGUMENT_KEY = "ExplorationManagerFragment.internal_profile_id"

const val TAG = "ExplorationManagerFragment.TAG"

    fun newInstance(internalProfileId: Int): ExplorationManagerFragment {
      val explorationManagerFragment = ExplorationManagerFragment()
      val args = Bundle()
      args.putInt(EXPLORATION_MANAGER_FRAGMENT_INTERNAL_PROFILE_ID_ARGUMENT_KEY, internalProfileId)
      explorationManagerFragment.arguments = args
      return explorationManagerFragment
    }
  }

NAMING CONVENTIONS :
INTERNAL_PROFILE_ID_EXTRA_KEY
INTERNAL_PROFILE_ID_ARGUMENT_KEY
INTERNAL_PROFILE_ID_SAVED_KEY (saved instance state)
