How to send rich content and session parameter fulfillment response from flexible webhook.

[shakil776]

Hi all, It is possible to send rich content and session parameter fulfillment response from flexible webhook?

I can send rich content using standard webhook but can't from flexible webhook. 

How can i send this response from flexible webhook response?

'fulfillmentResponse' => [
    'messages' => [
        [
            'text' => ['text' => ['This text come from standard webhook']]
        ]
    ]
]

Thank you
