Spider-Man, Deadpool came to the MCU through NWH, isn't affected by Strange's spell (either by healing/telepathic immunity or because of his Medium Sense) and doesn't get sent back.
The movie opens with him narrating a quick version of his tumble through reality, and cuts to him sitting with Peter in his little shitty apartment, recounting the story. With Peter sort of ducking and bobbing as Deadpool casually waves a pistol around. "Anyway, now that they're all caught up I better get going. Have to hurry if I'm going to beat animal control. Bye Tom, loved you in Onward, literal tears." As he dives like Spider-Man out the window and crashes down into the alley.
Negasonic Teenage Warhead.
Colossus needs to get mentioned as having to go deal with Putin, thus not able to make it for the movie.(maybe just a deleted scene, by 2024, this might not be relevant)
Nobody else.
