MH-ET LIVE Tiny88 setup

hello.
how can i use MH-ET LIVE Tiny88 with PlatformIO?
how can add this device to PlatformIO, and upload to this device?
with arduino ide program the way is on this link:

i dont know how to use it on PlatformIO

I personally have this board and it worked with a generic Tiny88 definition as e.g. supported with Generic ATtiny88 — PlatformIO v6.1 documentation. Make sure to change the clock frequency to 16MHz and the clock source macro (GitHub - SpenceKonde/ATTinyCore: Arduino core for ATtiny 1634, 828, x313, x4, x41, x5, x61, x7 and x8) (I don’t quite remember which one I used)

[env:attiny88]
platform = atmelavr
board = attiny88
board_build.f_cpu = 16000000L

; change clock source if needed
;build_unflags = -DCLOCK_SOURCE=18
; new clock source
;build_flags = -DCLOCK_SOURCE=17

upload_protocol = micronucleus

Thank you very much!
finely it work, I’m very happy…
