XIAO ESP32-S3 PlatformIO json file

Hello all.

Wonder if anyone has created the required .json file for PlatformIO so it can be used as the IDE for the XIAO ESP32-S3 board? Could you post it or provide a link if so?

Similar to the one for the C3?

Or, barring that, is there a way to extract the needed info from the boards.txt file and variants/XIAO_ESP32S3 folder from the arduino-esp32 core?

Many thanks.
