Webex has this as well, but I find that most people don't bother and just share their screen.

In the past I have liked marp (https://marp.app/) for technical slides as you write in markdown, can use version control, etc. Powerpoint always felt odd as a developer.

To share public slides I've published to GitHub pages (https://github.com/robalexdev/marp-to-pages). I've seen professors use it for all their slides. But that doesn't synchronize slides, last I checked.
