How to connect pi-top 4 to display screen?

So I have a pi top 4 and a keyboard and screen from pi-top. However the screen does not work when I boot up the Pi-top. Can someone please explain to me how to get this to work? Pics below with numbered components. Where does everything go? Thanks.

Plug cable #2 into the green port on the side of the pi top and the other end into the pitop display.

If you are using pitop OS it will work on first boot, if you are using any other version of Linux it won’t automatically work you have to install drivers.

You only need cable 1 and adapters 3&4 if you are plugging the pitop display into a regular computer
