[MCU] So… Are Doctor Strange and Wong’s existence public knowledge?

Minor Spoilers for Shang-Chi and the Legend of the Ten Rings.

In the movies, the existence of magic is generally kept hidden from the public eye by the Masters of the Mystic Arts through the use of the Mirror or Astral Dimension. But Doctor Strange and Wong don’t seem to be as hidden away as their fellow magic users, operating freely in New York as they please - They make portals out in the open, like busy streets or restaurants, they fight in underground battling rings, and they participate in battles like the Attack on Greenwich Village, which most likely was not conveniently empty of people with cellphones or something else. So are their existence still a secret? The Spider-Man: No Way Home trailer suggests that it’s incredibly unlikely that they could just do a magic spell to erase everyone’s memory of their existence.

In Far From Home one of Peter's classmates said Mysterio is like Dr Strange combined with Thor. It's likely that people only know him as the Avenger that can cast spells rather than as the Sorceror Supreme.
