You add a port to the public zone like so:

# firewall-cmd --zone=public --add-port=8080/tcp

Firewalld knows already many of the commonly used ports, so you might just use the service name instead:

# firewall-cmd --zone=public --add-service=kdeconnect

These changes won't persist over restarts. To make them persistent run:

# firewall-cmd --runtime-to-permanent

Or you might have used --permanent option in the original commands, but usually it's good to test your changes first.
