Can you access firestore client-side without firebase auth?

I have a counter in my react front-end that I want to display a document value from my firestore database. However, I can't seem to access the firestore data, the code below results in the following error:

Navbar.js (client-side code)

import { db, app, functions } from "./firebase";
import { getFunctions, httpsCallable } from "firebase/functions";
import { Link } from "react-router-dom";
import "../App.css";
import React, { useState } from "react";
import {
  getFirestore,
  collection,
  doc,
  getDocs,
  onSnapshot,
  getDocFromCache,
} from "firebase/firestore";


async function checker() {
  const querySnap = await getDocs(collection(db, "Count")); //Count is collections name
  querySnap.forEach((doc) => {
    console.log(doc.id, " => ", doc.data());
  });
}

Error Message

Navbar.js:28 Uncaught (in promise) FirebaseError: Missing or insufficient permissions.

I haven't implemented any firebase auth (although feels like I will need to implement before deploying), and I have tried adjusting my firestore rules (shown below, although I know they are too vulnerable).

firestore.rules

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

My goals are:

  1. Make a successful read of firestore data
  2. Adust security rules to be more secure
  3. Figure out if auth is necessary to add based on my needs here

Would appreciate any and all advice, I am still new to firebase.

Here is my config file if that is helpful?

firebase.js (in same directory as Navbar.js)

import { initializeApp } from 'firebase/app';
import { getFunctions, connectFunctionsEmulator } from 'firebase/functions';
import { getAnalytics } from "firebase/analytics";
import { getFirestore, collection, getDocs } from 'firebase/firestore';
import {getAuth} from "firebase/auth";


const firebaseConfig = {
  apiKey: //Hiding my data for this post
  authDomain: 
  projectId: 
  storageBucket: 
  messagingSenderId: 
  appId: 
  measurementId: 
};

const app = initializeApp(firebaseConfig);
export const functions = getFunctions(app);
export const db = getFirestore(app);
export const analytics = getAnalytics(app);


export default {app, db, analytics, functions};

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
