Keyboard, Touchpad and Touchscreen not working on Surface Laptop 3 with Ubuntu 20.04

I am trying to install Ubuntu 20.04 LTS dual boot with Windows 10 on a Microsoft Surface Laptop 3 13" Intel i7 but the keyboard, touchpad and touchscreen function do not work in Ubuntu at all. USB keyboard and mouse works fine in Ubuntu and the SL3 keyboard, touchpad and touchscreen function all work fine in Windows but not in Ubuntu. I can see the USB keyboard and mouse in the xinput list but I cannot see the SL3 keyboard or touchpad, is there a way to manually recognise these in Ubuntu or is not supported yet? As for the touchscreen function, I do not know what is causing this. I'm a newbie at this so any advice will be greatly appreciated.
