How to echo user select optionset from ChoiceSet using messageBack or imBack?

Question

I am trying to echo the user selected option from given set of user rating drop down using messageBack or imBack (whichever is possible). Since, I am only able to add a static text as value in messageBack value field

"actions": [
    {
      "type": "Action.Submit",
      "title": "OK",
      "data": {
        "msteams": {
          "type": "imBack",
          "value": "User selected option"
        }
      }
    }
  ]

Is there a way that I can get the value from choiceset and show is using messageBack on MS Teams?
