How can I give approvers the option to add a message to the person who submitted the form

I'd like for approvers to be able to tell submitters what they need to do in order to reach approval status.

Hi Shire_Gingin,

Thanks for reaching out to Jotform Support. Adding approval comments without the login option was temporarily disabled for approvers so that we could perform some security and stability improvements.

The option has now been enabled again. Approvers can comment without login to the account. We're sorry if this caused you any difficulties. 

Please see below:

Thanks for your patience, we appreciate it.
