Bridged Networking on Virtual Machine Manager KVM

Changed computers around now that I am more familiar with Zorin
Running Zorin 18 on a Dell Optiplex 5050 (32GB RAM) optimized for Virtual Machines.
2 NIC Cards
NIC 1 (Onboard) is for the 5050 It's self - will have nothing to deal with VM's
NIC 2 (PCIe) is strictly so the VM's can get on the network directly, The host doesn't need to use it.
-Zentyal will be installed it must have direct access to the network
-VitalPBX will be installed it must have direct access to the network
-Other VM's in time for other uses will be added which too will have direct access to network

I'm struggling to understand (what really should be a simple procedure) how to create a bridged connection in Virtual Machine Manager.

I've already ran in CLI below:
sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients virtinst libguestfs-tools libosinfo-bin bridge-utils

sudo adduser administrator libvirt
sudo adduser administrator kvm

(Rebooted)

sudo apt install bridge-utils NetworkManager-libnm

Virtual Machine Manager is installed and works under NAT.

Ran sudo nmtui

Brings up the menu options which thew me off right away.

I am looking for Virtual Switch Manager>(Virtual Switch name or create)>Connection Type>External Network>Realtek Ethernet

I don't understand why this can't be GUI based.
