Upload ESPHome firmware, I have already prepared the sketch but unable to upload, ESP32 doesn't go into flash mode

Please stop asking basic quesitons, I flash ESP since years so I'm well aware how it works !! What are specificities of that board to flash the ESP ? Do I need to maintain a button somewhere or do a short circuit to get ESP into Flash mode ?
