Connect running container to new network

[sullivan50909]

Is it possible to connect a running container to a new network?
I can successfully connect to one or more networks at the time I start a container using:
nerdctl run -it --net mynetwork1 --net mynetwork2 myimage
After I start the container, it is possible to connect to mynetwork3?
It appears that this is possible in docker using docker network connect, but the nerdctl docs say this command is unimplemented.
