Tiny USB depends issue

[AlexThePotter]

Fresh environment with empty setup & loops in main. Only arduino.h included.

.ini is :
[env:seeed-xiao-afruitnrf52-nrf52840-sense-plus] platform = https://github.com/h2zero/platform-n-able.git@^1.0.0 board = seeed_xiao_nrf52840_sense framework = arduino lib_deps = adafruit/Adafruit NeoPixel@^1.15.1

Gives error: In file included from .pio/libdeps/seeed-xiao-afruitnrf52-nrf52840-sense-plus/Adafruit NeoPixel/Adafruit_NeoPixel.cpp:46:
.pio/libdeps/seeed-xiao-afruitnrf52-nrf52840-sense-plus/Adafruit NeoPixel/Adafruit_NeoPixel.h:43:10: fatal error: Adafruit_TinyUSB.h: No such file or directory

From not finding built in tinyusb.

Adding tinyusb as a libdep gives this error:
.pio/libdeps/seeed-xiao-afruitnrf52-nrf52840-sense-plus/Adafruit TinyUSB Library/src/tusb_config.h:47:4: error: #error TinyUSB Arduino Library does not support your core yet
47 | #error TinyUSB Arduino Library does not support your core yet
| ^~~~~

Tried using the FASTLED lib instead and get this error:
44 | #include <nrf_nvic.h> // for Clockless / anything else using interrupts
| ^~~~~~~~~~~~
compilation terminated.

Thanks for all you do!

Looking for some help here - at the end of what i can think of to resolve this .
