Scenes or containers?

I’m working on a simple game inspired by titles like “A normal lost phone” or “Replica”. Basically they use the smartphone metaphor as a “interactive fiction” gameplay. One doubt I have is how manage with all the stuff or components of the game (bottom and top bar of the smartphone, the homescreen with apps icons, the apps themselves, notifications): as independent scenes or containers that depends of a “Phone” scene? Which option you think is better?

I recommend going with Phaser 3 independent scenes (mobile “toast”) instead of containers.
