Since Adobe Creative Cloud only supports the latest 2 versions of your apps, if you need an earlier version what do you do? Well the first thing you can do as an active creative cloud subscriber is contact support and ask for an earlier version.
The other thing you can do is go to ProDesignTools and check and see if he has the direct download links for the version you need. He has the links from 2019 to 2021, so you can still get 2019 if you need them (and if you are using them for a job, maybe it is a good idea to download their direct installers just in case as they are no longer available from the Creative Cloud app).
