Run fmriprep on a slice of data

Hello!

I am trying to run fmriprep on a slice of a large dataset (specifically, ADNI) where some but not all subjects have multiple sessions and in some cases, I want to use only some sessions out of the many a subject has – in short, I have a csv that is something like

subj,ses
ADNINNNN,mNNN

I am having a very hard time to understand how to use the bids-filter JSON on this, can someone provide a minimal syntax for say the following slice:
ADNI123,m000
ADNI456,m012

Thank you very much in advance!
