macbook Pro M1 pro 2021 3 external monitors connection problem

Hello guys. I have Macbook Pro 2021 M1 pro model, I want to connect it with 3 external monitors. Today I bought the Dell UD22 docking and installed DisplayLink drivers on my mac, trying to connect everything, but DisplayLink software doesn't recognise any input devices.

Here is how I am connecting my monitors:
I have 3x Lenovo P27h-20 monitors (yes, they have integrated dockings all of them but they do not support DisplayLink)

I am connecting two of them directly through USB-C ports to my macbook and the remaining one connecting through HDMI to UD22 dock (but I think USB-C should work as well), working with two is okay but my mac doesn't see the third one.

What could be the potential problem and how could it be solved? DisplayLink drivers are the newest and Macbook is up to date, MacOS Sonoma.

Appreciate the help.
