Seamlessly share Opening Slide and Opening Video at start of Webinar WITHOUT showing video controls?

Hi,

If I want to ramp up the professionalism of our webinar broadcasts, how can I seamlessly share Opening Slide and Opening Video at start of Webinar WITHOUT showing video controls or cursor? Any ideas for good software or any Zoom hacks to make multimedia sharing look more like a live mix and less like a fumble-fumble click-click high school presentation?
