Where were all Miles’ other friends?

One of the biggest head scratchers in Across the Spider-Verse is the absence of Spider-Man Noir, Spider-Ham, and Peni Parker. Peni appears briefly but the others don’t appear until the final moments. So, why aren’t those characters part of the Spider-Society when it seems as if basically everyone is, with the exception of Miles? Was it purposeful on Miguel’s part to keep them separated because of their allegiance to Miles? That seems like the most obvious explanation, one we hope gets cleared up in the next movie.
