Hi,
Thank you for reaching out. The manager accounts on the screenshot you provided are not necessarily in the same account hierarchy. Thus, it is not possible to fetch information for all of these accounts at the same time if they happen to be not in the same hierarchy. But if they are, you could use the highest level manager account to authenticate and give it a try to query the customer_client.id from the customer_client resource and set customer_client.manager to true in the WHERE clause.
Thanks and regards,
