The ability to create apps is an invited function. Users / accounts have to be invited by an OpCo representative to gain access to this feature. Typically, information for your OpCo can be found on Xerox.com. However, if you'd like to send the account information to the feedback Inbox (firstname.lastname@example.org), I can forward on the email to the group that can review and approve the request.
The following information is required:
Acount Email address
First and Last name of the account holder
Company of the account holder
