Is it possible to Connect Lenovo Desktop to a Lenovo USB-C docking station?

Hi
I recently bought a Lenovo Lenovo IdeaCentre G5 (running win 11) thinking it would be possible to use and share with my Lenovo ThinkPad USB-C Gen. 2 docking station. But when I connect the docking, it will only share mouse and keyboard. The monitors are not working. As far as I can see, there is no available free slot for a optional PCI-E thunderbolt card. I am stuck. Does anybody now any solutions, or options ? Is there any other desktops with option for extra 3.5” that also can utilize my Thinkpad USB-C docking?
