TypeError: messaging.getToken is not a function

So I'm working on a firebase cloud messaging web app and getting the error:

Error: TypeError: messaging.getToken is not a function

I tried a lot to troubleshoot it, searched on google too, but no luck. I'd be thankful if someone can help me.

The same code is working fine in the official google example. Below is the line where I'm getting this error:

            return messaging.getToken();

Error screenshot Below is the whole code:

import { getMessaging, getToken } from "https://www.gstatic.com/firebasejs/9.0.2/firebase-messaging.js";

const messaging = getMessaging(app);
    // Add the public key generated from the console here.
    getToken({vapidKey: "BBxqsbhYwDSfJ..."});

Got it, I had to import getToken method also. Below is the new snippet which I should have wrote:

import { getMessaging, getToken } from "https://www.gstatic.com/firebasejs/9.0.2/firebase-messaging.js";

instead of:

import { getMessaging } from "https://www.gstatic.com/firebasejs/9.0.2/firebase-messaging.js";
