Hybrid Webinar PowerPoint

[Marlark]

I have a hybrid event coming up next week. I'm bringing my Macbook Pro.  I can't find instructions on how to:

• Present a PowerPoint slide show on the in-room screen while also...
• Presenting the PowerPoint slide show in the Zoom webinar
• Control the Q&As and other webinar configurations without that showing on the in-room projected image

Maybe I should have the slides projected from a different computer and just run the same deck from my laptop with a webcam pointed at the speakers?

Any advice would be helpful. Thanks!
