Creative Cloud CC on OS 10.13.6

Hello, I am running OS 10.13.6 on an iMac 2010. The agent on Adobe chat was very helpfull, but advised me that I need at least system 10.15 to be able to run any available Creative Cloud software, that he can supply links for.  I am unable to upgrade, the hardware is too out of date. My Macbook was stolen, and I just need to use Photoshop CC and Indesign CC for a few days in order to get any work done, until my Macbook can be replaced. I was still running compatable Creative Cloud apps until January 2024 on this Mac. I am getting desperate trying to find a short term solution. Any expert advice will be greatly appreciated.
