AR Occlusion with Webcam Input UE4-27

I am using a realsense camera to get a live feed to which I want to add cg elements which I can interact with. This includes occluding cg elements which may be behind the user.
Is there any tutorial to achieve this?

Note: I don’t want to use green screens and need to achieve an interactive AR experience.

It’s probably too late, but if someone is faced with a similar task, then there are AR examples in this plugin
