Getting started with ESP32 S3 N8R2

I purchased a few of them and was puzzled trying to get it started in Platformio. First I was having problem loading a simple hello world code. After doing a combination on BOOT and RESET buttons, I was successful to get the code loaded. However, I could not see the message being printed to the terminal, then I learnt it from the forum and used the following in the platformio.ini. It works since then.
[env:esp32-s3-devkitc-1]

platform = espressif32

board = esp32-s3-devkitc-1

framework = arduino

build_flags =

-DARDUINO_USB_MODE=1

-DARDUINO_USB_CDC_ON_BOOT=1

monitor_port = /dev/cu.usbmodem14*

monitor_speed = 115200

monitor_rts = 0

monitor_dtr = 0
