To solve the problem of FirstFragment sharing its view model with its child fragments, you can use this code to access the FirstFragmentViewModel from any of the child fragments:

    // in ChildFragment1
    val firstFragmentViewModel: FirstFragmentViewModel by viewModels(
        { requireParentFragment() }
    )
