No bridge in VM setup

[roti]

Hello everyone,
I've just installed Proxmox on Debian 11 following this official guide.
I wanted to create a VM but there's no bridge available in the network configuration.

This is my /etc/network/interfaces:
source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

I also tried to create a bridge in the node>network section, but I don't have the knowledge to set them up.

Thanks.

A few screenshots below.

When installing via Debian you have to create the bridge yourself, there is a section on that in the guide you posted [1]
