links in How to create a bootable installer for macOS don't work

I need to create a bootable USB for macOS for Catalina, Big Sur, and Monterey. The links to download the OS do not work. I am on a Win 10 PC using firefox. The 6 work computers I have to update can not access the internet.

MacBook Pro (2020 and later)

any mac?

That Mac doing the download must be able to (theoretically) run the installer. E.g. very old Macs can’t download new incompatible system software.

For Catalina, the MacBook Air needs to be from Mid 2012 or newer.

For Big Sur, the MacBook Air needs to be from Mid 2013 or newer.

For Monterey, the MacBook Air needs to be from Early 2015 or newer.
