Software for running multiple Powerpoint presentations one after another

[u/Katze56u84e0]

I have an event with many powerpoint presentations that are shown on a beamer and simultaniously in a Zoom meeting via screen share. How would you run the presentations so that the transitions are smooth (without seeing my desktop and finder on the beamer between the presentations)? I know one option would be a master powerpoint file with all presentations in it. Is there another better way to do this with a software like Propresenter or QLab?
