How can I enable mouse look on a matinee camera?

I am just curious on how I could enable mouse look when the matinee camera is running. I would like to give the user the ability to look around with the mouse during the cut scenes. I have tried modifying the files CameraActor.h and MatineeActor.h, but nothing happened, and I don’t see a “compile code” option in my project. Can this be done through blueprints somehow?

I notice when I try to create a blueprint for one of the matinee cameras it doesn’t seem to function anymore.
