Unable to preview blocks interactively

[rayehizoba]

The underlying filament Builder class provides options for interactive block previews.
See: https://filamentphp.com/docs/3.x/forms/fields/builder#previewing-blocks

I've tried to enable this option, but it does not work. Kindly provide some pointers.

// AppServiceProvider.php

PageBuilder::configureUsing(function (PageBuilder $builder) {
      $builder->blockPreviews(areInteractive: true);
});

// MyBlock.php

class MyBlock extends PageBlock
{
    public static function getBlockSchema(): Block
    {
        return Block::make('my-block')
            ->schema([
                //
            ])
            ->preview('filament-fabricator.page-blocks.my-block');
    }
}
