Hello -
So the Blueprint above is a Camera Actor itself. I made a BP Actor class and added a Scene Capture 2D as the sole component. Once that is done, the important part of this is to set the Scene Capture 2D to not update on Tick via the Component Details and instead you will be using the logic listed above in Event Tick to run the same update functionality and finally and most importantly you are setting the actor to calculate Tick even when the Game is Paused on Event Begin Play.
Hopefully that clarifies what you are asking about -
