How to import a library in postman 'tests'?

Group,
I am trying to import a library to print current working directory in Postman ‘tests’ section? If I try with the below code

let process = require('node:process');
current_dir = process.cwd()
console.log('Current directory: ' + current_dir);

I get

There was an error in evaluating the test script:  Error: Cannot find module 'node:process'

My second doubt is, how do we import a user define library file? (Use case, I would like declare JSON schema variables in one file and have that used in all Postman tests by importing this JSON schema file)

Thanks in advance for the responses.
