Creating docker-machine using Docker Desktop

I am trying to create swarm using docker machine that consists of 3 managers and 3 workers. It works fine with Docker toolbox. However, it is failing when I tried to do the same with Docker Desktop

PS C:\Users\admin> docker-machine create

Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
