How can I use Network Manager to create a route to a docker Macvlan

Using https://lab4me.xyz/books/linux/page/how-to-create-and-use-macvlan-network-in-docker, I create a Docker macvlan network:

### create mac-vlan network docker network create \ -d macvlan \ --subnet=192.168.123.0/24 \ --gateway=192.168.123.1 \ -o parent=enp0s31f6 \ demo-macvlan-net 

and start a container on that network:

docker run --rm -itd \ --name alp1 \ --network=demo-macvlan-net \ --ip=192.168.123.111 \ alpine:latest \ /bin/sh 

All works fine, but as it says, we can't communicate from the Docker host to the container (though we can reach the container from anywhere else on the 192.168.123.0/24 subnet).

You can enable communication from the host via:

sudo ip link add mycool-net link enp0s31f6 type macvlan mode bridge sudo ip addr add 192.168.123.50/32 dev mycool-net sudo ip link set mycool-net up sudo ip route add 192.168.123.0/24 dev mycool-net 

(Actually, you can use sudo ip route add 192.168.123.111/32 dev mycool-net instead of the last command)

My most recent attempt using nmcli was:

nmcli connection add type macvlan ifname test mode bridge dev enp0s31f6 -- +ipv4.method manual ipv4.addresses 192.168.123.111 ipv4.gateway 192.168.123.1 

which gives me an ip route of:

192.168.2.1 dev test proto static scope link metric 411 

So, via the gateway, not the container's IP. If I don't specify the gateway, no route is created at all.

How can I create this macvlan in NetworkManager? Essentially, I need those last ip commands using nmcli (to make it possible to just activate a saved NM connection whenever I need it).
