Los profesionales de la agencia deben comunicarse con Amazon para solicitar acceso a las cuentas de Seller Central de sus clientes.

This statement is false. Agency professionals do not directly request access to client Seller Central accounts from Amazon. Instead, clients grant agencies access to their Seller Central accounts through a delegated user permission process within Seller Central itself. The client initiates this by inviting the agency's user account, allowing them to manage specific aspects like advertising campaigns. This method ensures that clients maintain control over who accesses their account and what permissions they have, without Amazon acting as an intermediary for access requests.
