UE4 Docs: Enable HDR Display Output Node Not Showing Up

I found a documentation page to enable HDR:

It showed this picture of a blueprint node to enable HDR:

https://docs.unrealengine.com/portals/0/images/Engine/Rendering/HDRDisplayOutput/HDRGameUserSettings.png

However, Supports HDRDisplay Output and Enable HDRDisplay Output is not showing up.
Is there a problem? Please simplify your solution; I’m kinda new to Unreal Engine.

Forgot the link:

I think I can do this. I watched a tutorial and I now understand the blueprint system more.

You may want to actually provide a summary of what the solution was (even in general terms) - so that other people can learn
