How can you use SteamVr Motion Controller Trigger in 2d game play?

I’m using the vive controllers for some virtual production tasks, and I would like to use the controller bindings during simulate or PIE playback, but not in VR.

The controller send tracking data which can be grabbed in blueprints just fine…but I’m struggling to get the button data off of the controllers when I’m not in VR mode.

Blueprints Key input nodes let me select vive trigger input, but it wont let me compile without error (you can’t do dat!)
I’ve tried several post recommendations with generating action mapping, but nothing gets through in 2d Play.
