Can afterStateHydrated know if new record or editing?

When using the afterStateHydrated on a select field in a form, can you know if it's in the modal for creating a new record or updating an existing one? I only want to set the pre-selected value of parent_id when creating a new record through the 'simple' resource manager but not when editing an existing record so the value of an existing records parent_id doesn't accidentally change.

Forms\Components\Select::make( 'parent_id' )
  ->options( self::getSelectParentChoices() )
  ->afterStateHydrated( static function ( Forms\Components\Select $component, $state, callable $get ) {
    //TODO Don't do this when editing an exisitng record
    $viewingParentId      = $component->getLivewire()->parent_id ?? - 1;
    $component->state($viewingParentId);
} )

Forms\Components\Select::make( 'parent_id' )
  ->options( self::getSelectParentChoices() )
  ->afterStateHydrated( static function ( Forms\Components\Select $component, $state, callable $get ) {
    //TODO Don't do this when editing an exisitng record
    $viewingParentId      = $component->getLivewire()->parent_id ?? - 1;
    $component->state($viewingParentId);
} )

$context should be available as an argument. then you can check:

if ($context === 'create') {
   ... do stuff
}

if ($context === 'create') {
   ... do stuff
}

or default

->default(function ($livewire, $component, $state, $get) {
    return ...
})

->default(function ($livewire, $component, $state, $get) {
    return ...
})
