New Developer - Trying to download CF2021

Hello,

Our current CF developer has suddenly resigned and I am tasked with getting up to speed with their CF environment to provide, what I would call bandaid support.  I am attempting to find a download for CF 2021, to create development environment on a PC.  However, all I am seeing on the Adobe website is downloads for CF 2023.  How does one go about trying to download previous versions of Coldfusion?

Thanks
