Can't see installed snaps on Raspberry OS

Hi, I’m very new to this but am struggling with installing Snaps. I installed snapd on my newly installed Raspberry OS. I tried running Hello World snap and everything seems to be working ok. However, I tried installing the Snap Store and also GNOME system monitor and eventhough I can find both in /snap directory, these apps are not appearing as installed in the Raspberry GUI. Any thoughts?
