Send on behalf of emails visible to the Sender mailbox.

Delegate is sending the email on behalf of the sender but actual sender can’t find them in the sent items.

In other words sent on behalf of emails are not showing in Sent Items of the Sender whose email id was used to send email and the email is showing in the delegate Sent Items. Now the problem is how sender would know what the email content was.
