EWS Request meeting as a user to book a room

Question

For this server, when a user attempts to book a room in Exchange, the room auto replies with an accept/decline. I am trying to replicate this process in EWS - using a service account to request a room meeting with a user attendee and a room resource. In order to have the room auto-reply to the user, and not the service account, do I need to use impersonation, or is there any other process? I am using php-ews for this, but any help in any language or what the SOAP request should contain would be greatly helpful.

You could request meeting using the below code:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages"       
               xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"       
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Header>
      <t:RequestServerVersion Version="Exchange2010" />
   </soap:Header>
   <soap:Body>
      <m:CreateItem SendMeetingInvitations="SendToAllAndSaveCopy">

                  <t:Attendee>
                     <t:Mailbox>
                        <t:EmailAddress>[email protected]</t:EmailAddress>
                     </t:Mailbox>
                  </t:Attendee>
