Buying home with FHSS

Bought a home at auction. Paid a deposit (borrowed money from a parent due to not having FHSS funds released). Funds from super account have been released and I have notified them that I have signed a contract to purchase. Can I use some of FHSS funds to pay back parent for them lending me money towards initial deposit? Or do ATO check that you’ve used FHSS funds towards home costs?
