""" Displays the VPN profile that is currently in use.
Left click opens a popup menu that lists all available VPN profiles and allows to establish
a VPN connection using that profile.
Prerequisites:
* nmcli needs to be installed and configured properly.
To quickly test, whether nmcli is working correctly, type "nmcli -g NAME,TYPE,DEVICE con" which
lists all the connection profiles that are configured. Make sure that your VPN profile is in that list!
e.g: to import a openvpn profile via nmcli:
sudo nmcli connection import type openvpn file </path/to/your/openvpn/profile.ovpn>
