Interesting Idea for engagement. Although I think slides suck in general and often used for one way communication, especially suck for Software Development. A doc is much more preferable and a lot of collaborative docs like Google Doc exist.
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.
Did you explore client-side for the presentation, and just do the collaborative part use a backend? Your backend doesn't really need to know whats on the screen to draw, nor to sync the slides, in my unverified opinion.
In a previous position, we used Adobe Connect a lot for online meetings, and the normal way of sharing presentations was to upload them to the room and control the presentation from there.
Webex has this as well, but I find that most people don't bother and just share their screen.

I wanted to first know if people would like something like this.
