type flatpak install nuvola eu.tiliado.NuvolaAppKexp and press the Enter key to install this package.
Then log out and log in back to let your desktop environment (Unity, GNOME, etc.) find out that
a new application has been installed. Otherwise, you may see "Unknown Application Name" in the menu bar,
mismatched application icons and other funny bugs.

Alternatively, you can launch KEXP Live Stream
from a terminal:
flatpak run eu.tiliado.NuvolaAppKexp
