Creating shortcuts of your most used applications that don't already create a shortcut to the desktop or gets deleted by accident, you can recreate it. You can do this for any application.
Here is an example to get Zoom onto your desktop. Zoom currently installs but doesn't make a shortcut making it hard to remember if you have it installed at all.
If you have Zoom installed. Click the Start button in the bottom left and type in "Start" or "Zoom" and you should have the app pop up in the search list. Right click the "Start Zoom" icon like below. If you don't see it then its probably not installed on your computer.

Then you can open file location and right click the shortcut > Send To Desktop.
