What would you do If some exchange transferred you $10 Million by mistake?

We all know this happened couple of times before, like Crypto dot com company accidentally transferred $10.5m to Australian woman and doesn’t notice for seven months. She then spent all the money thinking it's lord's gift to her. She later faced the lawsuit and we all know how.thats going.

If you wake up tomorrow morning and find 10 million in BTC transferred to you wallet, what would be the next step you are going to take?
