Concepts
Spaces and displays
Keep the same sessions on every screen, or pin each one to the Space it was created on.
One shared list, everywhere
By default, all your sessions live in one shared list, so opening the dock on any Space, display, or window shows the same set. Your list follows you to every screen.
Pinning sessions per Space
Prefer them separated? Turn off Same sessions in every Space in Settings, under Sessions, and each session sticks to the Mission Control Space it was created on. Either way, restored sessions are remapped so none are stranded.
