If doing this then it should install the needed snap (if not already installed) & perform the connection for the user

Test case:
Open Ubuntu Software
Search gnome-system-monitor
It will show it as not be installed (another bug, see screenshot?
Click to install
After install finishes click the launch button

What happens:
Nothing

User must install gnome-3-26-1604 snap & then run an obscure (to normal users) connect command
