Clips: Screen share and video - how do I appear ON the shared screen/presentation - not beside?

[Linsali]

Hello, I am desperate looking for settings where I can change the design of Clips recordings. I want to record my shared screen (powerpoint slides) and have the video of me talking on top of the presentation - not beside the presentation slides! Is it the only way to record in Clips - having your video beside the presentation? Problem is that the presentation will then get too small for the students to watch? I think that I somewhere could chose how the video/webcam of me would appear on the screen, but I have looked everywhere, cant find any settings. Please help! I need urgent help with this. Thanks.
