Is it possible in ue4? Interactive world-space Widget without changing focus/cursor lock?

I know that Epic have recently added in support for rendering UMG Interface Widgets in world-space.

But I can’t find a way to interact with the buttons, sliders et cetera using the point in the middle of the character view camera. I pretty much want to interact exactly like in this video here

But so far the only way I’ve been able to get any interaction is to show the mouse cursor, which then prevents the character camera moving until I click somewhere in the game window which is off the widget, re-focusing on the game which also causes the cursor to hide.

Is this possible at all? Or do I need to wait for Epic to extend the functionality of world-space widgets?

Ah, yes, that’s exactly what I’m after, thanks <-Quick down and dirty tutorial on how to get it up and running.
