Zoho Sign - Disable sending a document for viewing

Zoho Sign - Disable sending a document for viewing

Dear Community,

I'm looking to change the following behavior:

Currently when a user signs a document, he currently receives 2 emails from Zoho :
- An email with as an attachment the completed document - as per the email template "Notifying when a document is completed (with attachments)"
- An email with a link to the completed document - as per the email template "Sending document for viewing"

=> I would like to be able to only send 1 email with the attachemnt of the completed document but I can't find how 

Could you please help ?
