Need Photoshop CC 2019 to access Zoomify Export

System: MacBook Pro running macOS 15.1.1 (Sequoia)

The Zoomify Export feature (File > Export > Export As > Zoomify...) has been removed from Photoshop since version 22.1 (around 2020-2021).

I need it for a current project involving high-resolution zoomable images for the web.

I would like to install Photoshop CC 2019 alongside my current version (the latest one) in order to keep using Zoomify.

However, in the Creative Cloud desktop app, the oldest available previous version is from 2022 – nothing older like 2019 or 2020 is offered.

Adobe support in France told me that they cannot provide a direct download link for Photoshop 2019.

Does anyone here have a safe and official way (or link) to download and install Photoshop CC 2019 (v20.x) on macOS? I have an active Creative Cloud subscription, so activation shouldn't be an issue.

Any help or advice would be greatly appreciated!
