MAC address of IoT devices

Is there a means by which I can discover the MAC address of the various "Matter" devices connected to my Hubitat? When I installed various smart switches and so forth, via iPhone/HomeKit then linking to Hubitat, I didn't think at the time to note the new MAC addresses appearing on my router. Now I have a slew of "expressif" devices on my LAN that I'd like to identify, label (as defined in the Hubitat), and then block their internet access on my router. Since Hubitat communicates with them, I figured maybe it knows their MAC's and shows that somewhere? Or maybe there's an app for it? (Hubitat C8, latest firmware)

For my matter bulbs, Settings -> Matter Details. I have an IPv6 address for each Matter device. The last 4 digits match the last two hex values in their MAC addresses.

Didn't know that - What a useful tidbit!

Brilliant! Exactly what I needed, and especially thank you for that tip about the last 4 digits.
