Debian 11 Xfce - Applications -> Settings -> Network Connections missing

[Roger Price]

I'm trying to set up a Wi-Fi connection in Debian 11 with Xfce.  In previous 
Debian Xfce installations I found Applications -> Settings -> Network 
Connections which offered a useful GUI.  I can't find the Netwok Connections GUI 
in Debian 11.  Is there some additional package I need to install?

Command nmcli general reports that eth0 and wlan0 interfaces are operational, 
but I would prefer to continue using a GUI interface to set up wlan0 if this is 
possible.
