How can I add a attachment to the comment using rest API?

[Rohit Sarkar]

Currently I am using the API "https://<my jira url>/rest/api/2/issue/<issue Id>/comment" to post my comment to jira and the body that I am sending is 

"
{"body":"*qwert* _qwert_ \n+qwert+ \n****qwert**** ***\n*** \\!https://<my jirta url>/rest/api/2/attachment/content/10077\\!\n","visibility":null}
"

Ihave also tried with : 

{"body":
"*qwert* \n\n _qwert_ \n\n +qwert+ \n\n ****qwert****\n\n
<span class=\"image-wrap\" style=\"\"><img src=\"/rest/api/3/attachment/content/10089\" height=\"164\" width=\"160\" style=\"border: 0px solid black\" /></span>,
"visibility":null}

but it Doesn't seems to work.

Here I have already attached the attachment to jira and using the attachment Content URL  inside  "!<attachment content url>!" this works for discription field. 

how but not sure why its not working for the comment field can anyone help me with the response.
