specified, displaying the progress in the terminal window.
You can launch the application you installed like any other
application. If it's a graphical application, it should appear in your
desktop's applications menu. Otherwise, just start typing the
application's name at the terminal and press the Tab key to
automatically complete it. You can then press Enter to
launch the application or run the command you installed.
How to update a snap package

In effect, a .deb package includes an executable plus the information needed to install it into the system: where it goes, what it depends upon, etc. Compare this with a snap package, which includes the executable and any necessary dependencies - think of it like static linking of libraries versus dynamically calling in what's installed elsewhere on the system.
The idea is that you could have a stable version A library on the OS, but a new application might demand version B. With a .deb, you'd need to upgrade A, and that might in turn impact some other packages; with snap, the application would come bundled with version B for its sole use, so the system-wide version A remains untouched.
