EMG Notifications to Google Pub/Sub

Has anyone been able to successfully integrate EMG notifications with google's pub/sub? I have been at this for months and am not successful.
Basic path is:

EMG event such as port down is triggered
This event, which is picked up by the python outgoing notifications script located at https://github.com/equinix/messaging-gateway-templates/tree/master/template-python-outgoing-notifications-v1, which I have deployed as a cloud function and scheduled to run every 2 minutes, is then sent to pub/sub
the pub/sub notification is sent out as an email notification to my team.

Is anyone able to assist?
