The thing about snaps and app image is they are containerized.

Unlike snaps and flatpaks, AppImages arent containerized or sandboxed at all. They are only used to bundle (some) dependencies, so you don’t need to rely on packages provided by your distro’s package manager.

Because of the sandboxing, once you close the app it stops running in the background therefore there is nothing to get notifications from.

This can’t be caused by the sandboxing per se. I use many flatpak apps that keep running if you close all windows, eg. Amberol, Discord.

I don’t know if snap/Ubuntu has a “feature” that disables this behaviour
