How to use Power Point with the ATEM Mini (Pro)

I looked up several sources but for the most part, the infos I found are not helpful.
For example: I just want to reord a live stream on youtube where people can see me and my slides simultaneously.

What is the easiest way to do that?
Do you guys know any content that I can look up on how its done properly?

Thanks.

Connect camera and Laptop to ATEM, use a PiP.
