Long running action -> I would like to trigger an overlay spinner until action completes

[vesper8]

I have some Nova actions that take 5-10 seconds to execute and I want to A) prevent the user from navigating away or interacting with the page until the action is finished running and B) give some kind of indicator (a simple spinner) that the action is actually in the process of running.

A progress bar would be even better but a simple spinner will do. I notice there is such a spinner when you run delete a resource so I know the functionality is there, is there already a way to add a spinner to actions?

Many thanks
