How to use my computer off-shared-screen while hosting a zoom-call? (Windows)

[Christo68]

Hi, how can I use my computer off-screen while hosting a Zoom call or webinar? I keep struggling with this. It's like when I use Zoom, Zoom takes over my system, but I still want to be able to e.g. search for things, or read from sources on my computer, invisible to my webinar participants.

I want to be able to lead a Zoom call, all the while being able to access my computer, without sharing that with the people I have the Zoom call with. I want to be able to have both shared and non-shared content accessible to me simultaneously, on Windows. 

I am using an external monitor. How can I dedicate e.g. one monitor to the Zoom call, and the other to stay off the call, with my normal computer functions available to me?
