As the Link in the original Dokumentation that i found was not longer available i searched through a few ebay and amazon offers.
Finaly i found something in an ebay auction from DIYmall. The link contains a ~400MB Zip file with the SDK toolchain and some examples more then in the std esp32-arduino package.
Here i found a oled example where the think with the Pin16 pullup was added compared to the std esp32 libs.
i will not add this zip file here or on github cause it seems like there is some copyright violation ( i'm sure it is xD ) triggered here.
But i will upload some off the examples after i took a look at them
