It is based on the typical process from Espressif webpage. I use VSCode plugin, which is almost "install & play".

https://docs.espressif.com/projects/esp-idf/en/v4.3/esp32/get-started/vscode-setup.html

Basically, build button, put the device in DFU mode and flash button and voila. DFU mode could be quite tricky, but my board has BOOT and RESET buttons, which enter in DFU when pressed both same time (similarly to RP2040).

If you are interested only in flashing, you can use ESP32 Flasher tool at https://www.picokeys.com/esp32-flasher/ which will flash your board without downloading any framework. Just put it in DFU and click on Flash.
