Download an earlier version of MacOS on a Mac with later OS

When I try to download an earlier version of MacOS on my Mac that has OS Ventura, I get this message. "Install macOS Monterey" cannot be opened from a newer version of MacOS. For more info visit: https://support.apple.com/HT2011372

If I wanted to create a bootable OS on ext drive to install on another Mac how can I obtain a copy? In trying to wipe the Mac ready for sale I have managed to wipe the OS and now get the folder with a ? on start up! I have tried all the Key combinations on Start Up and all result in failure including the revolving world asking for WiFi settings which run for a while then stop.

MacBook Air 13″

Well it's true it can't be opened. However, once quit, "Install macOS Monterey" should be in the Applications folder and can be used to create a USB Bootable Installer.
