Campaigns endpoint lastUpdatedTime

Hello,

The data returned from

/email/public/v1/campaigns

has a

lastUpdatedAt

field. Could I get some clarification as to what counts as ‘recent activity’ (as described here: https://legacydocs.hubspot.com/docs/methods/email/get_campaigns).

I am noticing that the timestamps from the API response don’t seem to match the UI’s ‘Last Updated’ column. Does the field in the API response describe when the last open, click etc. event occur vs the one in the UI describing when the campaign itself was modified?

I can provide reproduction details in private if necessary of course.

Thanks in advance!
