PackagesNotFoundError: The following packages are not available from current channels

[VictorPoreeFr]

I attempted to install the program Larch using the following commands :
conda create -y --name xraylarch python>=3.13.9
conda activate xraylarch
conda install -y -c conda-forge numpy scipy matplotlib h5py>=3.10 wxpython>=4.2.2 mkl_fft

I get an error message about mkl_fft. So I tried to install it following the ml_fft recommendations but get the same message :

$ conda install -c https://software.repos.intel.com/python/conda mkl_fft
