I have created a simple workflow with an approval process. After creating a new custom list item, the workflow assigns a task for a specified user for accepting or rejecting this new item.
By default, the approver can click Approve or Reject button.
How to add a textbox, so the approver can write a reason for approving/rejecting the entry? And how to insert this reason to a proper column in this new item?
It is Sharepoint 2013 workflow model.
