Can OKX reverse a transaction?

Excuse me, I have a question regarding OKX's capabilities. I'm wondering, in the event of a mistake or unforeseen circumstance, is it possible for OKX to reverse a transaction that has already been completed? I understand that transactions on blockchain networks are typically irreversible due to their decentralized nature, but I'm curious if OKX has any processes or mechanisms in place that could potentially allow for such a reversal, especially in cases where there's been a clear error or fraud involved. Thank you for your time and consideration.
