Cine camera Focal Length control

Hi, I’m trying to make a player controlled camera that has the ability to change focal lengths and lens settings
I’m using a cine camera as it has all the setting I want, but my problem is I dont know how to access the the settings that are in the details panel from my Blue Print.
I’ve got a working control system and HUD so all I need to know is how do I link my inputs to the focal length and lens setting?

Thanks for helping
