Like the title says, anybody know how to do this? This is how it used to work on my Note 9. I'm using the Z fold 6 now, and the app that I'm on gets "zoomed out"/no longer stays open (you can see what I mean in the images).
Task switcher on Note 9, the current app remains visible in the background.
