You can find the MAC address of your device in a few different places:
On the device packaging: Look for a label on both the sleeve and the brown box.
During device onboarding: If you're setting up your device, the MAC address will appear at the lower left corner of the "Let’s get connected" screen (it's the one with a red background and two hands trying to shake).
After onboarding: If you've already set up your device, go to Settings › Wi-Fi and scroll to the bottom of the list of networks to find the MAC address.
Hope this helps! If you have any questions or need further assistance, feel free to reach out.
