Chat Plugin creates gap on the frontend bottom

Hi WPMUDEV Heroes

The Chat plugin on our site in Frontend creates a gap on the bottom. How can we move that up so that this gap is not existing. Any ideas?

Even better would be if we could place a Chat Icon with the Chat stuff displayed in the icon just beside the to top and the contact form modal bottom.

Thanks Andi
