Is it possible to take the video from the screen and the camera separately from the user via zoom / skype?

Question

YouTube

The essence of the question is in the title, maybe there are alternatives - the task is to get a separate image from the webcam and a separate video from the screen from users with a small amount of effort, then it will be relayed via OBS to youtube

Ps By the way, there may be options simpler than OBS with a small budget (2-3tr per broadcast / month) - I will be grateful
