Sharing a report from Kibana to Slack

Good afternoon.

I need to do something but I can't find how. I have an automated report in Kibana (from a Dashborad, so the report gives me a PDF). I need this report to be sent to a Slack channel on a daily basis.

I can do it from the alarm section from kibana (I have already some monitoring alerts created and they are being sent to a slack channel daily with no problems), but I can't find the option to do the same with the reports. Any help, please?
