Message pop up when closing/leaving dashboard page
This may be a long shot but I was wondering if there was any kind of functionality to have a message appear if you leave a dashboard page/try to close out of it. The use case is that I have a dashboard that has a button that is hitting when a conference call happens and it updates security groups so certain users can't make updates during the call. I have another button the user SHOULD hit when the call is done and this will put the security back to what it was originally. If the user of the dashboard forgets to hit that other button at the end of the call then the security never changes back. Was hoping to give a pop up message or something that forces the user to hit that end call button so the security goes back to what it was.
