Kaimon.jl fails to install on Julia LTS 1.10.10

This is on a windows 11 system for Julia 1.10.10:

(jl_zQXCQD) pkg> add Kaimon

└─Kaimon [d3856c55] log:

Is there specific code in Kaimon.jl that prevents use with the julia LTS?
I notice that the CI says 1.12+

I can’t say whether it uses features or dependencies which are only available for Julia 1.12 but the README and the Project.toml are quite clear on only Julia 1.12 and later being supported.
