LyraT does not appear in the list of ESP32 Arduino Boards

[Volcano]

Hi ESP32 experts,

I am new to ESP32. I got a LyraT board and added the ESP32 library to the Arduino IDE by adding "https://dl.espressif.com/dl/package_esp32_index.json" to the "Additional Boards manager URLs". However, when I go to Tools->Board: "Arduino Uno"->ESP32 Arduino, Isee many ESP32 boards listed there but the "ESP32-LyraT" is not among them.

How can I add the "ESP32-LyraT" to the list of ESP32 boards in Arduino IDE?

Thanks,
Volcano
