Platformio board = pico or rpipico2 for Raspberry Pi Pico 2?

[frohro]

I am a bit confused. I am using the Arduino-Pico framework and started playing with the Pico 2 and Pico 2 W. I use VScode and in the PlatformIO Home
under Platforms it says the board id is rpipico2,

but if I use what it tells me instead of pico for the board in platformio.ini, I get

Resolving raspberry_pi_pico2_serial dependencies...
UnknownBoard: Unknown board ID 'rpipico2'

I suspect this is because I don't fully understand the difference between the board and the platform, and don't trust the AI enough to believe it. I am adding multiple configurations to my platformio.ini for several different boards and then building the code to make sure it will work for each of them. I discovered that the Pico and Pico 2 had the same env in my platformio.ini, so I am suspicious that my code may work for the Pico, but not the Pico 2. Is this the correct env for the Pico 2?

Here is my platformio.ini for the Pico 2.

[env:raspberry_pi_pico2_serial]
platform = https://github.com/earlephilhower/platform-raspberrypi.git
board = pico  ; This is strange, but I can't find why not rpipico2!
framework = arduino
board_build.core = earlephilhower
lib_deps =

build_flags =  
    -US302_WEBSOCKETS
    -DS302_SERIAL
    -D CORE_DEBUG_LEVEL=5
; Optional: specify USB settings for Arduino-Pico
;board_build.filesystem_size = 0.5m
;upload_protocol = picotool

Thanks for the help!!
