I followed the documentation to try the notification system of Laravel 5.3, but I just cannot display the values of the "data" column (message and action).

In this column, the data is saved as json encoded array (?) in a text field:

{"message":"New comment on your photos.","action":"\/photos\/9372"}

How do I access these values in a blade view? This does not work:

@forelse($notifications as $n)
    @php
        $data = $n->data;
    @endphp

    {!! $data["message"] !!}
@empty
    nothing
@endforelse

It says "index not found". I have tried lots of variants with json_decode and without, but can't get it to work.
