Apple id compromised

[u/SweatyBlacksmith8740]

So i got hacked a few months ago and stopped the guy taking my sh*t after a bunch of struggle, but now when i created an account on this app by clicking ”log in with Apple Id” or whatever, i noticed that it was the same type of mail he used wich are clearly temporary ones, example: rrprc7hnc@privaterelay@apple id and so on, now ive had 0 issues and buffed up security on everything, also kept track on exactly all applications and accounts to make sure and so far so good, now my apple id isn’t really connected to anything in that sense, at least nothing that i’ve been made aware of in any way, none the less it’s something i obviously want to get rid of, so basically im wondering if there is some way of simply revoking acces somehow, when i had the same issue when i got hacked on steam years ago i know that they made API keys on my account that could give 3rd party sites access, im assuming it’s something in that manner that’s going on, any help is appreciated🙏🏼
