CLM External Review done via email, where does the email text reply go?

I am using the external review step in a workflow and I have enabled in the account the option to reply to the external review directly via email.

I am testing the external review and If I reply via email without a document, just with a reply saying for example that document is ok, I do not find the Reviewer reply anywhere. 

If I reply within the link and comment in the comments section, those comments are saved correctly, but if I reply directly from the email my external reviewer reply is not visible anywhere.

I would expect that email reply to be saved in the external review comments but it is not happening. Am I missing something? Where can the submitter see what the external reviewer replied via email? I only see in the workflow the output of step as “Completed without document”.
