Cannot install proplot

Hello,
I am on OSX 14.6 and I am using Python 3.12.6 (main, Sep 6 2024, 19:03:47) [Clang 15.0.0 (clang-1500.3.9.4)] with Matplotlib 3.9.2. I want to install proplot, but I can’t.

I tried

 % pip3 install proplot

Do you know how to get this to work ?
Thank you

The PyPi page only claims support up to 3.8.
You might want to ask the developer for support.
