Update confirmation email from completed Update Request

edited 12/09/19 in Smartsheet Basics

We have noticed when using an Update Request that the Requester and Requestee (who completes the update) BOTH get an automatic email "Update Confirmation."  Our Requestees do not want to receive the automatic email confirmation (after all, they know they have just completed the update request).  Does anyone know how to eliminate that for the Requestee?  I have not been able to find it as a setting or anything.  

Thank you.
