Looking for MAC address on Kidde Smart Smoke + CO2 Alarm

This device is used with Ring but when I look at the details of the device within the Ring app, it doesn't reveal to me the MAC address and IP address of each of my 7 Kidde smoke detectors that I just purchased. I figured I download the Kidde mobile app but when I scan the QR code from within the Kidde app, I thought I would be able to see my device within the Kidde app but instead it tells me to go to the Ring app. But the Ring app doesn't reveal within the Device Health for each of my Kidde smart smoke detectors the IP address or MAC address. I need the MAC address. Does anyone know how I get this from this device? I've reached out to Kidde and they suggested to contact Ring since this is managed and maintained through the Ring app. Thx.
