As Administrator, I cannot see other users' documents in Acrobat Pro DC with enhanced e-sign

My organisation is subscribed to Acrobat Pro DC with enhanced e-sign.
We are two separate users in the same organisation. I am the system administrator and the other person is an account user. 
The other user's signed/completed documents are not accessible or visible for me.

I would like to have access to the other user's documents from my account login. 
I'll appreciate guidance about how to activate access to other users' documents in my organisation.

Thanks in advance for any assistance.
