I want to invite a freelancer to my agency but I don't know their Usernames or email

UPDATE: I already spoke to Sandy from Support, she said this is not the best way. Therefore I decided stop and not to move on with this. 

My Question:

I have an agency I'm trying to recruit few people to join my agency and work for a client

I need someone from Latin Americas and I don't know anyone from there.

How can I bring them to my agency?

Can I ask them for their usernames within the UpWork Message center?

Is that allowed? UpWork has limited information regarding this.

Could you pls clarify this.

As far as I know we are not allowed to ask freelancers with their email. Does the same policy applies to asking a freelancer with their User Name?

ANSWER: You can only invite freelancers on your agency if you know them and know their username or email.
