Edit message before forwarding

[Arkadiusz Alicki]

Hi,

I need to get the last message from thread and forward it without message body (I need to forward attachments only). How can I edit message body before I send it? 

I need only attachments from the message, and currently attachments + inlineImages are being forwarded. 

I can not do it with .sendEmail() method, because i want to preserve thread history. 

Here's snippet of the code:

else{

          lastMessage.forward(forwardingAddress, {

            from: fromAddress,

            subject: subject,

          });

      }

Hi,

To clarify: 

We have label in Gmail Inbox, and all those messages within that label should be forwarded to external Application. I created a time-triggered script which sends all those messages, but the problem is that Inline Images get send too (signature images, header images from message etc.) - I only need to forward PDF file attached to the mail, not with extra inline Images.
