Arducam UC-788 Rev.B OV9281 not detected when connected to RPi 4B

I have an Arducam UC-788 Rev. B with OV9281 sensor (SKU B0224) , UC-693 connection ribbon and Raspberry Pi 4B 8 Gb with Bullseye OS.
Linux pi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linux
I’ve connected camera and installed libcamera according to the Quick Start guide Quick Start - Arducam Wiki
Unfortunately, camera is not detected with
ls /dev/video*

Tested with 2 cameras, 2 RPies and different Raspbian versions (Buster/Bullseye, 32 and 64 bit versions)

What have I missed?
