mne-BIDS NIRS gain matrix

Hi, here are my setup details :
Platform: Windows-10-10
Python: 3.9.7 (default, Sep 16 2021, 16:59:28) [MSC v.1916 64 bit (AMD64)]
mne: 1.0.2
matplotlib: 3.5.1 {backend=module://matplotlib_inline.backend_inline}
mne_nirs: 0.4.0

I used the mne-bids-pipeline to change my NIRx data to BIDS format, it worked fine but the BIDS format doesn’t seem to be keeping the gain matrix as a parameter. I would be useful to have it to explore how a channel gain impact the fnirs signal quality.

Question about how MNE-BIDS handles NIRS data.
