Will SU Pro work on Mojave at all since no longer supported

I am stuck on a late 2012 IMac and Mojave awaiting the new M-chip 27”. I want to start using Pro, but am afraid it will not work at all. Is that the case, or will I just be missing some of the new updated tools? Thanks

I’m currently using 2020 on a daily basis with High Sierra and that works fine. 2021 is installed and seems to run in a quick test. I believe you can with subscription download and install the last three versions which right now are 2020, 21 and 22.

Thank you
