Possible to show an authorization-like modal from a d-bus call?

I’m making a custom authenticator and I’d like to show the user a confirmation box before triggering it. I know one way is to write a small daemon that listens to events and pops up a dialog box, but I was wondering if there’s a way to invoke the gnome-shell dialog with a d-bus call instead?


Could Polkit be what you’re after?
