Hello,
In Google Ads I can go to Audience manager, click on a customer list, click on Segment Members, and I get a list of uploads:

I understand I can retrieve this information in a report from resource
offline_user_data_job. Now, above screenshot shows a column "date". How can I get the date of an upload, as this resource doesn't appear to support that?
My aim is to report when recent upload(s) fail or when no uploads for a user list occurred for some time. The resource appears to show all uploads, but _not_ the time of the upload. Am I looking in the wrong place?
Background:
I work for an agency. The client uses -I think- Salesforce which is actually doing the upload with Google Ads API, not us. Sometimes this fails but the problem is not reported to us, still the client wants us to warn them of this situation.
Sample code about uploading this information all do the upload themselves, retrieve the Job Id of the upload, then check every now and then about the progress. But we do _not_ have a Job Id to check. How do we get the date of the Offline User Data Jobs?
