Hello! I try to apply the code below for ESP8266 to ESP32 C3, with forked library for ESP32 but doesn't work

https://github.com/sinricpro/ESPTrueRandom

Can you help with a solution?

I'm trying uuid https://github.com/RobTillaart/UUID library but I don't know How to use can you help me?

Have you another solution?

Thank you
