Downloading Reports from Manager Account

[cachatj]

I am trying to download a custom report made on ads.microsoft.com; which is made up of several clients (n=150) under control of a single Manager Account.

1. If I want to use request_report.py as a starting point, where can I inject the custom report name or report_id in order to download a single csv file?

2. looking at auth_helper.py (below), would I use my Manager account_id as the UserId? Also, if my first time running the script I logged into the wrong account, how re-log in to change the account_id its currently using (which is wrong) vs hardcoding the account_id (which is commented in) to one of the accounts under our management?

    # Set to an empty user identifier to get the current authenticated Bing Ads user,
    # and then search for all accounts the user can access.
    user=get_user_response=customer_service.GetUser(
        UserId=None
    ).User
    accounts=search_accounts_by_user_id(customer_service, user.Id)
    
    # For this example we'll use the first account.
    # authorization_data.account_id=accounts['AdvertiserAccount'][0].Id
    # authorization_data.customer_id=accounts['AdvertiserAccount'][0].ParentCustomerId
    authorization_data.account_id = '########'
    authorization_data.customer_id = accounts['AdvertiserAccount'][0].ParentCustomerId
