Generating a report can take a while. User should be notified through the notification drawer when his/her scheduled report is complete and ready for download. The notification should have a link to download the report. The report is stored for a limited time window (1 day), if it's already deleted at the time user clicks the link, he should be informed it's no longer available and offered to generate it again, which redirect to the report template repo with the right report template preselected. That information can be fetched from the task input.
