No, in the usage-based pricing model, only the meeting host will be considered an active host when a meeting with Pro features occurs.
Please note that the delegate will need to have Pro permissions to schedule meetings for another user and have access to the Scheduled meeting assistant or the Amazon Chime for Outlook add-in. The delegate will only be considered an active host if the meeting ID used is associated with their Amazon Chime account.
