'best practices for imessage link previews / open graph images?
is there any documentation on best practices for imessage link previews? I know that when there are multiple open graph / og images provided, imessage will coalesce them into a grid layout.
I can't find any docs on best dimensions and file sizes for these images, or how the number of images affects the grid layout.

the latest documentation I found is from 2017, and it doesn't cover multiple og images. https://developer.apple.com/library/archive/technotes/tn2444/_index.html
