Blueprint Pop-Up info box?

I’m trying to create a UI that will open when you get near it. I can see an example of it in this video Unreal Engine 4 | Blueprints Office Demo | GTX 780 Ti - YouTube at about 20 seconds in, but I’m just wondering what component it is so I can look into implementing it.

I’m unsure if it’s a custom blueprint or an in-built one. Any help would be appreciated, thanks.

Well you can actually download that project in the video from the Epic Games Launcher and check it yourself. It is under the Learn tab in Engine Feature Samples. It is called “Blueprints”. The object you want is called “BP_Commentary_Box”.
