I have a couple of relevant articles you may be interested in ...
On assigning the zone via NM:
https://www.hogarthuk.com/?q=node/8
Look down to the "Specifying a particular firewall zone" bit ...
remember that if you edit the files rather than using nmcli you must
reload NM (or do nmcli reload) for that to take effect.
If you specify a zone in NM then this will override the firewalld
configuration if the zone is specified there.
Here's some firewalld stuff:

Don't forget that if you use --permanent on a command you need to do a
reload for it to read the config from disk and apply it.
