Need LrC v 10.x

[JT25714890n6io]

Monterey computer died, was able to replace with 27" iMac with highest OS Big Sur (11.7).  I accept that my old library is useless but that is fine, I can rebuild.  No money to get new iMac at the moment. 

I downloaded CC installer but can't find a way to dl/install LrC v 10.x, I am just shown the v 13.x and "not compatible" - the three dots do not get me to earlier versions.

Am I stuck? 

Thanks

I have LrC 12.5 installed on my iMac 27" mid 2015 with BigSur.

Is there a specific reason you need LrC 10.x

My bad, had googled what is latest verison compatible with Big Sur.  I'm fine with 12.5.

Thanks all,  once I bought Photography subscription I had access to 12.5, have also added LR (cloudie) and am now workng my way through my images.,  Fortunately I was also at v12 on old Mac so my v12 library is readable and all my edits are still there.
