How do you move the webcam location in a shared screen multi monitor recording?

I give courses to students and I want to record them.

I have 2 monitors so I have the webcams on my right screen and my left screen is shared for the presentation.

But when I record and view the result my webcam is always in the top right corner.

How do I change this?

I do want my webcam to be shown in the recording, but on the left side.

I cannot find anywhere how to adjust this.
