[HelloDB]

Thank you for your library, how to expose the onboard external flash memory as USB Mass Storage?

There is no API for that, and all depends what partition would you like to expose. I think the easiest would be to expose FFat, but anyway you need to add some functions or try to use esp-idf. In this repository is very simple and not production ready implementation to expose OTA partiton, which allows to update with drag n drop: https://github.com/chegewara/esp32s2-msc-ota
