Is there a way to display more than 5 buttons in Amazon lex-v2 response

This is my sessionState object

{
"sessionAttributes": {},
"dialogAction": {
  "type": "ElicitSlot",
  "slotToElicit": "flowName"
},
"intent": {
  "name": "WelcomeIntent",
  "confirmationState": "None",
  "slots": {
    "flowName": null
  },
  "state": "Fulfilled"
}

this is messages array

[
{
  "contentType": "ImageResponseCard",
  "content": "Some content",
  "imageResponseCard": {
    "title": "Choose option",
    "subtitle": "options are",
    "buttons": [
      {
        "text": "option1",
        "value": "option1"
      },
      {
        "text": "option2",
        "value": "option2"
      },
      {
        "text": "option3",
        "value": "option3"
      },
      {
        "text": "option4",
        "value": "option4"
      },
      {
        "text": "option5",
        "value": "option5"
      },
      {
        "text": "option6",
        "value": "option6"
      },
      {
        "text": "option7",
        "value": "option7"
      }
    ]
  }
}

]

iam sending 7 buttons from lamda function, but lex is not accepting more than 5 buttons. It is giving error saying buttons should be between 0,5 index. Is there way to display more than 5 buttons in lex response.
