Iftop lan name resolving

I'm using iftop to monitor bandwidth, sorting by dest host basically to show which LAN device is using how much bandwidth with the following settings file

interface: br-lan
promiscuous: yes
hide-source: yes
max-bandwidth: 85M
line-display: one-line-both

However, all my dest hosts are in IP format - i.e. 192.168.1.etc

I'd like to display my LAN IPs by LAN host name. I.e. I'd like my computer to be listed as "JON-PC" instead of (not a static address, but neither static nor dynamic address are looked up)

Openwrt recognises these names - anywhere DHCP leases are displayed in openwrt, the lan host names are also displayed. How do I get this to work in iftop as well? I've tried lots of options in iftop, for example -n, but doesn't work

I am running openwrt 21.02.3 and adguard, but otherwise, a pretty default configuration

Is this called reverse DNS lookup?

Thanks for help

'OpenWrt 22.03.0-rc5 r19523-bfd070e7fa'

I installed the package and decencies for iftop .
Assigned (Added) static addresses to everything on the br-lan and ran with the -n option and everything that had a mac address and IP (configured in Static) showed the DNS Resolution.
