Adobe CC has removed all the older versions of Premiere Pro and I'm stuck!

Hello everybody. Writing here after having a frustrating chat session with the adobe customer service. So I updated my creative cloud desktop app on my Mac and all of a sudden I see that the app has removed all the older versions of Premiere Pro that were earlier available for download at the click of a button. We all know how diffrerent edit studios have different versions installed and one really can't work with just one standard version in such an environment. Plus there are personal preferences of editors too where they like to edit on a particular version. 

However that's no longer possible from the Creative Cloud app. If you want to install an older version of PPro then you have to contact the customer service online and they will provide a download link IF it's available and that too only of the base version.  So you will get a link for say Premiere Pro version 22 but will no longer get any link for it's sub versions like 22.6.2, etc.

And that's where I am now stuck. I wanted to downgrade from 22.6.3 to version 22 for a project and with the help of the customer service I could do that. However this meant that as soon as I download version 22, version 22.6.3 will disappear and that's fine. But to my horror, there's now no way for me to upgrade to the sub version of 22.6.3 which is the last version available on MacOS Catallina. Neither from the creative cloud app or from the customer service. Even thet had no sollution to this and they actually asked me to post it on the adobe community support for help instead of solving the problem. So can anyone please tell me how can I get the 22.6.3 version of premiere back on my system? I'm not paying a bomb to resort to third party pirated websites and cracks for this. Will really be grateful if someone can help me out.

It's really frustrating that Adobe didn't even bother to intimate their customers prior to making these changes all of a sudden. Avid had given prior intimation before taking their older versions off from the download center but Adobe just doesn't care at all for their customers. And it's even more frstrating when all of this happens in the middle of juggling different projects!
