Is there a seperate bar while sharing screen?

I wonder if Jitsi has a seperate bar while I’m sharing on the screen of my share. Can I see the participants? I mean a bar like this: https://ibb.co/N2XgGgL

And I wonder if Jitsi has a whiteboard feature like zoom?

You can try it yourself on meet.jit.si.

Nope there is no such feature, I know people were experimenting and embedding etherdraw
