Is there a movie where the female lead is very powerful, but she hides her identity and lives in the eyes of ordinary people?

Many movies had female leads like this, such as the female lead in Black Widow, Scarlet Johann. She was a superhero who hid her identity and lived in the eyes of ordinary people. She was a special agent with superb combat ability and skills, but she had always hidden her identity and only kept in touch with a few people. In the movie, she became a well-respected hero by carrying out missions and protecting humans.
