Creates a new reply to a comment. The content should be in a valid HTML format.

Example content:
"<p>"Hello World!</p>"
Result:
Hello World!

Mentions can be added directly to the content field. However, a HTML attribute is required to achieved this. The required mention HTML attribute looks like:
"<span class="mentioned-user" contenteditable="false">{email_to_mention}</span>"

Example content with mentions:
"<p>"This needs some changes <span class="mentioned-user" contenteditable="false">@[email protected]</span>!</p>"
Result:
This needs some changes @[email protected]!

Note that it will throw an error if the email is not a member or doesn't have a role on that instance the reply is being added.

Note: Currently reply to a comment can only be added to a content field resource. This will expand to more resource types in future releases.
