Can we customize cast?

Hello everyone I’m trying to become a streamer but I’m on a very low low budget and I’ve found that using casting save on the storage. I have been casting and using obs to record my gameplay since I can’t use airlink due to my specs not being high enough. But I can’t customize it to eye like in the camera but it would be nice if I could. Please let meta see this cuz it would be nice it they could do this soon.
