I'm not sure what's in the workshop, but the list of supported devices in the Google Matter sample code can provide you some ideas for ESP32 device compatibility.
A single LED would be on a different pin, driven by a different protocol, and would likely require a different Matter lighting endpoint sans color and brightness, in addition to the CPU differences (unless you did your own PWM).
