4. Press and hold the "0" button on the ESP32-S2 and only then connect it to the PC, "ESP32-S2" should become available as a connection, select it and hit "Connect"
5. In the "Device Dashboard" select "Install Tasmota"

FAQ

1. Why not simply use the tasmota online tool to upload the *.bin directly? -> tried but did not work
2. Why not simply upload the firmware in step 9. before connecting to the network? -> tried but this failed due to memory constraints
