Switch build error : namespace missing 'SwitchProControllerHID'

I am trying to make a switch build for my project, but I keep getting this “namespace ‘SwitchProControllerHID’ could not be found error”. I have attached the screenshot of the error. The namespace SwitchProControllerHID (UnityEngine.InputSystem.Switch) does exist in my project, and can be located but somehow during build it is marking it as missing.

Unity Version : 2020.3.0f1
Switch SDK Version : 11.4.3
Unity New Input system Version : 1.0.2
Build platform : Nintendo Switch
Api compatibility level : .Net Standard 2.0

For consoles there’s a SDK-specific plugin for the Input System. Because it’s under NDA, you can find it in the developer portal. Or it’s already been downloaded along with the SDK, and you’d have to copy the files into the project.
