O365_connect_azure_to_ucs_user does not work anymore

We are trying to connect existing Azure AD users to existing UCS users. There is a script linked here:
https://forge.univention.org/bugzilla/show_bug.cgi?id=48641

This script has worked in the past but fails with an error message on startup now. Probably since updating the connector to the latest version.

$ ./o365_sync_existing_users 
Traceback (most recent call last):
  File "./o365_sync_existing_users", line 34, in <module>
    from univention.office365.azure_handler import AzureHandler
ImportError: No module named azure_handler

Is anyone here aware of an updated version?
