Old Sonoff Dongle to Matter & Zigbee with eWeLink CUBE?

I was think of buying a new Sonoff dongle so I could use some Ikea Matter remote controls for devices at home. I have a Sonoff Dongle Plus - apparently now called a ZPDongle-P, which is not compatible with Matter.

When I was looking at the Sonoff site, I saw reference to software called eWeLink CUBE.
This software implies you can link it to the old dongle and get Matter and Zigbee devices connected. Am I misreading this?

Their blurb:

What Does the Dongle Enable in CUBE OS？

With the Dongle, CUBE OS becomes a powerful local Zigbee hub, letting you pair lights, switches, plugs, and sensors with ease, bridge them into Apple Home, Google Home, Alexa, or SmartThings through the Matter Bridge, and enjoy a unified smart home experience without coding, without YAML, and with fully local, privacy-friendly control.

I tried the AI route on this and I am left with the impression that what CUBE does is bring Zigbee devices into what you might call the “Matter Dashboard” so you can see all the Zigbee and Matter devices together. But it does not make the -P dongle work with Matter devices.

That might be AI misinformation, but…
