Customer Care Facebook and iOS?

Hello everyone. I’m very concerned about a thing that happens to me often. There is a bot that always sends me messages to send my Apple acount info on messenger, otherwise it will shut down my facebook account. It even happened once, because I didn’t give it my apple info. Is it a scam? Is it for real? The messages say to not share the codes with anyone! I’m genuinely scared. I don’t wanna lose my fb account, but at the same time i don’t want to get my privacy violated.
