This is not the right place for the button. It implies that you email people who already answered the survey and/or that the selection in the list below applies to what this button does. But it simply emails all the event participants!

Maybe a new action box item below "Survey is live" would be a good place?

Maybe we could also get rid of the "Send links" dialog (which is using the old one) for private surveys now that we have a new one that can do the same? The only main change we'd need is adding an option to enter custom email addresses (and maybe making "send to event participants" just an option so you can choose either of the two).

But maybe this is more something for a separate PR...

Yeah I also thought about replacing the other dialog, but doing it in another PR is probably better
