3.3.5.4. How to Download a Chat Attachment 
In a chat conversation with attachments, you can see a mini preview of attached files
(images,
audio or video files), the file name and the size.
Tap on an attachment to download it. Tap again on the attachment to either open it
in-app (in
case of an image file) or open it with a suggested system application.
Downloaded attachments are also available in your configured downloads’ folder where
you can
perform all the usual file handling actions (e.g., share, copy to another
folder, etc).
