DisconnectMessage with Icon?

When a Web App disconnects, it shows a hazard icon with the DisconnectMessage text.

Is there a way to show my Web App icon there instead of the hazard icon?

See https://forum.xojo.com/19069-change-the-page-the-application-has-gone-off-line-please-try-ag/0 where Jay Madren posted a method to do so.

Thank you! I searched and didn’t find that.
