If you don’t have one created prior you would just use your shortcut above to create one, once you do it instantly pulls you to the new desktop. Otherwise if it does already exist just use your other shortcuts to switch between them easily.
Also, for future reference once you switch to the 2nd desktop here is another shortcut for you: Ctrl+Shift+Esc <–this opens Task Manager for you
