Snap-Store install for Debian seems incorrect

https://snapcraft.io/install/snap-store/debian This page says to:

sudo apt update
sudo apt install snapd
sudo snap install snapd

however when I do this I cannot find any snap software searching the store or by using the xdg-open method via the snapcraft.io website unless I also install: sudo apt install gnome-software-plugin-snap

So why is this step not included in the Debian install page?
