CC2020 is the last version compatible with this version of MacOS. However, this version is not supported by Adobe anymore nor neither have they shared it's public download link. If you want this version you can contact Adobe support and ask for an installer, if they have it available they would share it.

If you can work with CC2019 then you can download it's installer from the following website
