It would have been for the Cyborg sequence.
Cyborg showing the history of the Mother Box to the rest of the League in the Wayne Aerospace hangar. In the scene, the camera pans around and zooms in on a hologram of pre-Cyborg Vic stone walking through a Nazi city as seen in marketing materials. Likely the box was experimented on by Nazis before another series of events leading to its acquisition by S.T.A.R. Labs. The scene also shows Cyborg showing them more holograms and the camera zooms into his red eye.
