How could I implement a smooth movement like this in UE4?

I was watching this and as you can see his view doesnt immediatly rotate but lags behind making for a very smooth movement. How could I implement this is in ue4? I tried spring arm but it lags around weirdly. Here the mouse moves to the corner and the camera drags after.

Any help more than appreciated! cheers.

Install the 3rd person template. Select the in view hero model.In the BP detail panel select “CameraBoom”. In the Boom detail panel scroll to “Lag” and enable and set the desired lag values

Press play and enjoy
