FAFSA and Foreign Income Exclusion

I can find older discussions on this issue…but nothing that seems to address it recently with any clarity.

Parents and student are US Citizens. All live abroad as expats.

Parents file US Federal taxes and taxes in their country of residency.

Parents get the foreign income exclusion for the federal taxes.

HOW is this addressed in the FAFSA? If someone could just walk me through this I would be ever grateful.
