Open Ubuntu Browser from Terminal

Very simple question:

How do you open the Ubuntu Internet Browser from the Terminal?

I am running a computer through an X-forwarded session, and need to find the command to open the Ubuntu Browser. It isn't my default browser, so sensible-browser doesn't open it. I tried:

browser
ubuntu-browser
gnome-browser
sensible-browser
brow*

They all returned Command not found, except sensible-browser, which opened chrome.

Solution 1:

It's actually webbrowser-app

nano /usr/share/applications/webbrowser-app.desktop

The .desktop file
