How to enable screen sharing on in regard to FaceTime?

[youngrapper]

I got tip that there's option to enable screensharing between two people on FaceTime but I don't know where to enabled it on iPhone nor MacBook, can you help please?

I'm obviously misunderstanding your question because when you FaceTime someone, your screen is automatically shared with the person you're FaceTiming and vice-versa.
