Process Contingent Workers as External Candidates

Summary:

Hi all,

Has anyone ever changed this setting after golive?

2 requirements are specified in this guide Implementing Recruiting

We would like to know what means the second requisite "Users (including employees) aren't active on Oracle Fusion Cloud Recruiting. This is to avoid the creation of any new candidate job applications."
How should employees not be active? Does it mean that they do not have to access the recruiting pages during following processes?

Thank you,

Alessandro.
