Box folders being made visible within my box user account, rather than only accessible via the admin console for Salesforce Integration

Hi
I have Integrated Salesforce with Box in which the folders are creating under the admin console(via Salesforce) with help of Box Apps snapshot attached to below 
I want to implement same functionality but folder needs to be created at user level via Salesforce. Please suggest me ways to create app at user level or folder at user level though salesforce API. Attaching snapshot below (currently visible folder in snapshot are created through box directly not through salesforce)
