Recording with two hosts showing at once and not participants- using powerpoint

Hello, I am needing to record a presentation done using PowerPoint on zoom. There will be a co-host and I need both host and co-host videos (or rather thumbnails) to be shown on the side. However I cannot have any of the participants thumbnails showing at the same time in the recording. This is especially important for confidentialitya s this will be recorded and shared. So no other participants showing bu the host and co-host and the powerpoint presentation as the main screen. Can anyone help? Ive done everything from pinning to spotlighting t o changing my setting in the backend, nothing is working and my $250 a year to zoom still makes me ineligible for help...;-/
