Form Task attachments



We  new to Nintex  and using SharePoint 2016. I have a question or issue.  We are using flexi-task for our approvals.  We have a form that has 8 levels of approvals.  Following a different post, I configured a web server call to grab the attachment from the list and show the attachment on the flexi-task form  for each approver so this is working fine.   Here is my issue, during the approval process, some approver will need to add an attachment to the form.  This attachment should update the form and should show when the next approver receives the form task. 

I read about the post below but is not working and I am not sure if this will apply to me.


Can someone help me or guide me step by step on what to do?


Thank you so much, I really appreciated!
