Whats the best way to communicate ideas in remote meetings?

We are fully remote and every time I need to explain something, i start talking and people zone out or ask me to slow down, so I have to end up pulling up docs or screensharing and walking through every step. Last meeting took 45 minutes for what should have been 10.

I tried writing it out ahead in long docs but then they say its too much to read before the meeting. And since everyone is on different time zones its hard to schedule without messing up productivity.

I see a lot of ppl mention online whiteboard visual collaboration tools and infinite canvas stuff for this, but im not sure which ones actually cut the time down.
