What is a proper way to pass additional parameters into Hidden element from the ownerRecord?

I have a self referencing Category model (id, parent_id). All of the Categories and Sub-Categories belong to the single Menu model. I am using RelationManager to solve the self referencing relationship but not sure how to pass menu_id from the ownerRecord during creation of a sub-category. Here is how my RelationManager looks like.

class ChildrenRelationManager extends RelationManager
{
    protected static string $relationship = 'children';

    protected static ?string $recordTitleAttribute = 'title';

    protected static ?string $title = 'Sub-Categories';

    protected static ?string $modelLabel = 'category';

    public static function form(Form $form): Form
    {
        return $form->schema([
            Forms\Components\Hidden::make('menu_id'),       // <--- need to pass menu_id from the ownerRecord here

            TranslatableKeyValue::make('title')
                ->languages(['lt', 'en'])
                ->required()
                ->autofocus(),

            Forms\Components\FileUpload::make('image')
                ->nullable()
                ->image()
                ->directory('categories')
                ->acceptedFileTypes(['image/png', 'image/jpeg']),
        ])->columns(1);
    }

class ChildrenRelationManager extends RelationManager
{
    protected static string $relationship = 'children';

    protected static ?string $recordTitleAttribute = 'title';

    protected static ?string $title = 'Sub-Categories';

    protected static ?string $modelLabel = 'category';

    public static function form(Form $form): Form
    {
        return $form->schema([
            Forms\Components\Hidden::make('menu_id'),       // <--- need to pass menu_id from the ownerRecord here

            TranslatableKeyValue::make('title')
                ->languages(['lt', 'en'])
                ->required()
                ->autofocus(),

            Forms\Components\FileUpload::make('image')
                ->nullable()
                ->image()
                ->directory('categories')
                ->acceptedFileTypes(['image/png', 'image/jpeg']),
        ])->columns(1);
    }

I have ended up with this but not sure if there is a better way to achieve the same. 🙂

            Forms\Components\Hidden::make('menu_id')
                ->afterStateHydrated(function (RelationManager $livewire, Forms\Components\Hidden $component) {
                    $component->state($livewire->ownerRecord->menu_id);
                }),

            Forms\Components\Hidden::make('menu_id')
                ->afterStateHydrated(function (RelationManager $livewire, Forms\Components\Hidden $component) {
                    $component->state($livewire->ownerRecord->menu_id);
                }),

You probably shouldn’t use hidden but a lifecycle hook if this shouldn’t be manipulated by the user
