Hi Adam,
Thank you for raising this concern to Google Ads API Team.
To answer your question "How I can get the subAccounts numbers from my manager accounts?", you can get the account hierarchy of your manager account, by building a Google Ads Query Language statement to query all the child accounts specified by the client_customer field from CustomerClient, and executing it recursively on the sub-manager accounts. You'll be able to check which accounts are directly linked to your manager account and which are indirectly linked through sub-managers. For more information kindly check this document.
Best regards,
