while changing transition in a jira ticket i want to comment internally as it is a mandatory field.

can you help me with that

[Crazy_Infoscion WariD]

{
   "body": "Test internal comment",
   "properties": {
     "key": "sd.public.comment",
     "value": {
        "internal": true
     }
   }
}

tried using this but it helps in commenting internally in a separate comment

and 

{ "body": "Hello there", "public": false}

 this too doesn't works
