Running 1st-level after fmriprep

[orenpapers]

Hi,
I ran fmriprep on my own dataset, which is in BIDS format.
So now have all of the preprocessing results on

derivatives/fmriprep/sub-00X/

folders.
I want to use the preprocessed data and apply 1st level on it -
however, it seems that the example:
https://miykael.github.io/nipype_tutorial/notebooks/example_1stlevel.html
Does not support this kind of structure and I am not sure how to feed it with the preprocessed data.
How can I use your 1stlevel example on post-fmriprep data?

Thanks!
