Parallels icons on MacOS desktop - make them disappear?

I don't like the icons of the parallel running Windows 10 desktop appear also on the MacOS desktop.
Can I suppress this?

Why do I have two icons in the dock of the MacOS desktop? One is named Parallels Desktop and the other is named Windows 10.

Under "Parallels Desktop" I would expect something allowing me to do settings for Parallels in general, not the guest OS appear.

Beside this I find the two red bars ugly from the designers' standpoint of view.You should consider a different way of giving it the "Parallels" brand.

Actually, how do I get into the parallels application at all? Under VMware I start the workstation of some other application allowing me to create new VMs etc. Where do I do this in Parallels ?
