How do you add forms created by Sub-Account Users to the Account Owner's library?

I am an account owner and one of my sub-account users created a form that I now want to have accessible in my Forms Library. I also want to be able to clone it.  It's not automatically visible and it doesn't come up in my search, and she can't figure out how to share it with me other than give me the collaboration link.  

Thank you.

The "sub-user" simply needs to drag and drop his forms into the folder that has the name of your account username, example: https://www.jotform.com/help/342-How-to-transfer-or-share-forms-and-data-with-another-account
