Form doesnt work with builder blocks and blockPreviews

public static function form(Form $form): Form
{
    return $form
        ->schema([
            Forms\Components\Builder::make('content')
                ->blockPreviews()
                ->blocks([
                    Forms\Components\Builder\Block::make('test')
                        ->schema([
                            Forms\Components\TextInput::make('title')
                              ->default('Test')
                              ->required()
                        ])
                        ->preview('test'),
                ]) 
        ]);
}
