Unable to download Windows 10 on to my iMac

I want to download Windows10 on to my iMac (late 2013) running Os Catalina using Bootcamp. I follow the link from Apple's instructions to Microsoft and get the following message from Microsoft "You’ve been routed to this page because the operating system you’re using won’t support the Windows 10 media creation tool and we want to make sure you can download Windows 10. To use the media creation tool, visit

the Microsoft Software Download Windows 10 page from a Windows 7, Windows 8.1 or Windows 10 device. You can use this page to download a disc image (ISO file) that can be used

to install or reinstall Windows 10. The image can also be used to create

installation media using a USB flash drive or DVD." This is self defeating as I don't own a Windows device. If I had a Windows device I wouldn't need to download Windows on to my Mac.
