Currently, there is no requirement to complete the 'A Comment" field on an approval request. If a request is denied, we are looking for a response as to WHY for the requester.
without the requirement I was going to build a workaround to build an automation if the a comment column was left blank and the status was declined a follow up request would go out for the declined reasoning. Unfortunately plans were spoiled when i realized the a comment response is being loaded into the conversations not a new column on the sheet that can run automations.
Request to either require the response when loaded or move the comment responses into a column in the sheet.
