We have a requirement to start downloading attachments stored in another non-Pega application.

We can retrieve the file contents and information through a service and we already found a way to do so using the "Open URL in window" action on the link, but our client is asking if it possible to do so without opening a new window or a new tab.

Is there any way?

Since the attachment is stored outside Pega, we cannot use "pega.ui.HarnessActions.doAttachmentSingleClick" script.
