Provide send/receive date of an email in Outlook add-ins

As described in this https://stackoverflow.com/questions/57252812/how-i-can-get-received-date-of-my-mail-in-office-js we need the possibility to get the send or receive date of an email in our Outlook add-in. Currently there are only dateTimeCreated and dateTimeModified available (https://learn.microsoft.com/en-us/javascript/api/requirement-sets/outlook/requirement-set-1.12/office.context.mailbox.item?view=powerpoint-js-preview).
