Persistent global banner and/or all-user message

I need to send a message to all users on an instance of Grafana. I’m happy to consider any approaches that accomplish that, but what comes to mind is essentially a banner that appears on all pages, somehow. Is there a way to do that? Or, is there some other way to do that? Perhaps a popup that users would see and acknowledge, whatever works. Thanks in advance.

There is no built in messaging system. This is of course easy to do if you fork Grafana.

If you do not want to fork Grafana, an option would be to create a custom Home dashboard with your message and set that for the Grafana org. 1. Create custom dashboard 2. Star it 3. Go to Org preferences 4. Change the Home Dashboard field to your new dashboard.:
