Is it safe firebase-messaging-sw.js in public folder

Question

We have Laravel Application which uses Firebase push notification. For this we have placed "firebase-messaging-sw.js" file inside the public folder and it can access via URL and can view the "firebase-messaging-sw.js" file content.

This file contain following information

const firebaseConfig = {
  apiKey: "XXX",
  authDomain: "XXX",
  projectId: "XXX",
  storageBucket: "XXX",
  messagingSenderId: "XXX",
  appId: "XXX",
  measurementId: "XXX"
};

Is it safe showing API Key and other information in public? OR what is the correct way?
