upwork how to add a freelancer to the agency?

Answer 1

apparently go to his profile and send him an invite from the agency.

Answer 2

I myself encountered such a problem - you can add either knowing his login on Upwork, or the email to which the account is registered.
If it is possible to contact a person not through Upwork - ask him directly about the email\login.
As an option, create an employer company under your account, post a job vacancy and invite this person.
