Protractor: Run tests using environment specific params from CLI

I am working on a protractor typescript testing framework and would like to run tests in different environments depending upon the env specific params that I send in CLI. For example: I want to run my test as "npm test SIT" or "npm test dit". The base url picks the url for SIT in case 1 and DIT in case2 to launch the application in different SIT and DIT environments.

I have made a file name Url.js(root/ data/ Url.js)

'use strict';
var env = browser.params.environment;

module.exports = {
  baseURL: function() {
    var baseUrl = '';
    if (env.toLowerCase().indexOf('sit') === -1) {
      baseUrl = 'https://'+env+'-site.com/app/home';
    } else if(env.toLowerCase().indexOf('dit') === -1){
      baseUrl = 'https://'+env+'-site.com/app/home';
    } else if(env.toLowerCase().indexOf('rit') === -1){
      baseUrl = 'https://'+env+'-site.com/app/home';
      }
    return baseUrl;
  }, 
  internalPage1: 'app/page/details/fff/ttt.html'  
};

Here is my config.ts

let path = require('path');
import { browser, Config } from "protractor";
import { Reporter } from "../support/reporter";
import * as oracledb from 'oracledb';
const jsonReports = process.cwd() + "/reports/json";


export const config: Config = {
    params:{
        environment: 'fdi', //dit or rit can be passed from cmd line        
    },

    seleniumAddress: "http://localhost:4444/wd/hub",

    SELENIUM_PROMISE_MANAGER: false,    

    capabilities: {

        browserName: 'chrome',
        maxInstances: 6

    },

    framework: "custom",
    frameworkPath: require.resolve("protractor-cucumber-framework"),

    specs: [
        "../../features/automation/regression/*.feature",
    ],

    onPrepare: () => {
        browser.ignoreSynchronization = true;
        browser.manage().timeouts().implicitlyWait(12000);
        browser.manage().window().maximize();
        Reporter.createDirectory(jsonReports);      

    },

    cucumberOpts: {
        compiler: "ts:ts-node/register",
        format: "json:./reports/json/cucumber_report.json",
        require: ["../../typeScript/stepdefinitions/*.js",
         "../../typeScript/support/*.js", 
         "../../dbUtils/index"],
        strict: true,
        tags: "@dataTable",        
        restartBrowserBetweenTests: true


    },

    onComplete: () => {
        Reporter.createHTMLReport();
    },
};

Cucumber hooks:

const { BeforeAll, After, AfterAll, Status, setDefaultTimeout, Before  } = require("cucumber");
import * as fs from "fs";
import { browser } from "protractor";
import { config } from "../config/config";
import { build$ } from "protractor/built/element";
var env = browser.params.environment;

//setDefaultTimeout(600 * 1000);

Before(async function ()  {
    await browser.get(env);
});

After(async function(scenario) {
    if (scenario.result.status === Status.FAILED) {
        // screenShot is a base-64 encoded PNG
         const screenShot = await browser.takeScreenshot();
         this.attach(screenShot, "image/png");
    }    
});

 AfterAll(async () => {
     await browser.quit();
 });

I dont know if I should call Url.js in my config.ts, I think I do but I am not sure how that could be done. Could someone give me some pointers as to who I can nail this down?
