Doctor Strange in the Multiverse of Madness (includes spoilers)

Who was that guy he spoke to? That bit completely confused me. Was he supposed to be somebody of some significance?
I think he's one of the doctors from the first movie?
He was also credited together with the rest of the main characters dd. I was puzzled.
It was Nicodemus West, the villain in Brian K Vaughn’s and Marcos Martin’s Doctor Strange: The Oath mini. Not sure if they’ll do anything with him though.
