API- How can we get the sent date of an campaign activity?

Hi,

We've been using this endpoint Get /emails/activities/{campaign_activity_id} to get campaign activities detail information but noticed that it doesn't give us the date that an campaign activity was sent out instead of created date. Is it possible to get that "sent date" included in the response? I can see the UI displays the sent date on each campaign. Why wouldn't we include that in the endpoint response? It would be more helpful to have the "sent date" than "created date".

Thank you.
