Can an Upwork agency be used as a platform for non-Upwork freelancers?

Question

Freelance

Tell me please. Do I understand correctly that it is quite possible (not against the rules) to use an agency on Upwork for a non-Upwork team? That is, I have X freelancers, this team will do the project, but its members are not registered on Upwork. It's not against the rules, is it? If so, then running hourly tasks - just like a manual clock?
Thank you very much in advance.

   8. AGENCY POLICIES
   Every person working on behalf of an agency must have their own account and profile. These profiles must be associated with their agency on Upwork. Sharing accounts is not permitted.

   How do I apply on behalf of the agency as a whole?
   Although the Connects balance is shared by the whole agency, proposals are submitted on behalf of particular workers. You cannot “apply as an agency” without assigning the proposals to a person.
   it is forbidden

Answer 2

Conducts directly from your why do you need an agency for this

Answer 3

however, the policy does not forbid you to take the project as a freelancer and then hire other freelancers outside the exchange to provide your work (for example, designers).
it's just that these other freelancers are not allowed to use the tracker and other upwork infrastructure
