Different Apps have different versions. Photoshop is 22.51, InDesign is 16.4 etc.
The Creative Cloud App is available only in the latest version as of my knowledge. Creative Cloud Programs like Photoshop are only available in the latest major version and all subversions of thereof and the major version before (the latest subversion only).
ProDesignTools, however, maintains direct links to the installation programs of different Adobe program versions. You may or may not find a working direct link to what you're looking for there: https://prodesigntools.com/. ProDesignTools links directly to Adobe's servers, so the links may or may not work, depending on Adobe's websites.
