How to make QubesOS secure VM?

I want to create a VM in QubesOS environment. As you do not know how to make, please tell in detail.Since I want to use an anonymous secret VM and KeePass exclusively for Tor browser via Tor, please teach me how to create a local secure VM that does not connect to the Internet.Also, I would like to add an application or VM as an icon to the screen like Windows, so please tell me how.
