Needs a Laser Pointer!
Laser pointer! When sharing a whiteboard, the other members can't see my mouse pointer, so it would be great to have a way to point to things you've drawn or written on the whiteboard without having to physically draw, then erase.
I have bad experiences with the mouse pointer in video conferences. The pointer keeps smaller for the participants, even when the presenter has configured a very large one. This difference is relevant when the presenter has a very large monitor (with large pixel definition). You can see that in the attached picture.
I think mouse cursor is intuitive and perfectly acceptable. Keep it simple.
Mouse coursor is not enough - please inspire by Jamboard - line that gradually disappears

I think the whiteboard should allow participants' mouse cursor to be seen by others, then it can be used as a pointer, just like the Miro web board.

As a workaround, I draw a pointer,select it as an object
and drag it around, parking it when not needed
