Thanks for the contribution. I modified the rule a bit to use correct fields. You can check it in #4888
Just note that i'm not cloud nor an entra expert. I used the linked tweet and did some extra research to make sure its as accurate as possible. If you or a future reader find an issue. Please don't hesitate to fix it.
