Marvel DC Crossover

Is there a post credit scene in Dr Strange Multiverse of Madness ?

Doctor Strange in the Multiverse of Madness to release in USA on May 6, 2022  

Doctor Strange In The Multiverse Of Madness has a major post credits scene that teases towards some big things in the future of the MCU

In it we get Clea and present danger as we learn that Stephen is a Doctor Who has caused an incursion 

This is a major thing in the Marvel Universe and it's all leading towards Secret Wars. 

Clea played by Charlize Theron 

Now there's two endings to the film. The first one being where we watch Strange walking down the street 

before he collapses and an eye shoots open in the middle of his forehead. 

This would be a big cliffhanger to end things on however the post credits scene follows him once more walking down the street and everything seems fine. 

It is possible that this is actually a variant strange but the world around them looks exactly like New York so I do believe it's the main one from the MCU.
