Here krunners can use createRunOptions for creating an options window, but trying to find examples on that I found that none of the official runners use that, however one of them uses K_EXPORT_RUNNER_CONFIG, which I can't find all that much documentation on. And my the configuration button for my runner doesn't show up in krunner.

So what's needed exactly to get an options window to show for a custom krunner, and whats the preferred way of doing it?
