How to use the 40 pin connector

Hello.
I'm desesperatly trying to use the up4000 40pins connector. The goal is to drive an i2c display. OS is ubuntu 20.04, could change to 22.04. I can't find anything that works, even mraa says "No pins", when I use "mraa-gpio list"
SOS.

Yes, I did. (on another post I showed uname -a
Linux up4k01 5.4.0-1-generic #0~upboard5-Ubuntu SMP Fri Jan 7 11:53:57 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
and a gpiodetect which shows # gpiodetect
gpiochip0 [INT3452:00] (78 lines)
gpiochip1 [INT3452:01] (77 lines)
gpiochip2 [INT3452:02] (47 lines)
gpiochip3 [INT3452:03] (43 lines)
gpiochip4 [Raspberry Pi compatible UP GPIO] (28 lines) (<= I think this is due to 5.4.0-1 Kernel)
