I need to download a extra large file from AWS S3. To do this I generate a one time signed URL in a microflow and open a blank page with URL Redirector (https://appstore.home.mendix.com/link/app/113/) as the last activity of the microflow. The redirector works great, but I end up staring at a blank page. Ideally, I need to return back to the calling page, i.e. close the blank page with URL redirector. I suspect I need to initiate a microflow once the URL redirector completes its action. Can somebody guide me how to achieve this?
