Set the item to "USB memory stick" so that the MediaCreationTool downloads Windows and copies it to your stick.

If you want to create a USB stick from the MediaCreationTool, it must now be connected to the computer. You can then select which stick you want to use. The stick must have at least 4 GBytes of memory, preferably more. The wizard then downloads the Windows 10 installation files and copies them to the USB stick or to the ISO file.
