How to teleport from ingame menu in VR-template

I know how to open the menu, but I haven’t figured out how to make it appear in front of the VR camera. I also haven’t understood how to update the location of the playercontroller in the widget blueprint. On the other hand, I can’t do anything based on the trigger in the widget blueprint, because the OnEvent custom trigger isn’t showing there. However, it does show in the actor viewport, but there I can’t tell the OnEvent trigger if the widget button is pressed or not. Was that understandable? I’m fairly new to UE4, but have a good understanding of the terminologies.
