Missing BroadcastService in @azure/[email protected]

Question

I'm trying to update MSAL Angular v1 to v2 now, but have had some problems. One of them is that BroadcastService is missing in V2.

I have followed this guide, but none mentions what an equivalent of BroadcastService is in V2. https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-angular/docs/v2-docs/v1-v2-upgrade-guide.md

I found MsalBroadcastService in V2 repository, but not sure how to migrate it.
https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/b315d95797810241224a3cf118e67a1a723adec7/lib/msal-angular/src/msal.broadcast.service.ts#L13

My current code is something like this.

this.broadcastService.subscribe("msal:loginFailure", payload => {
    // do something here
});

this.broadcastService.subscribe("msal:loginSuccess", payload => {
    // do something here
});

Apparently MsalBroadcastService is the replacement, and I found the sample of usage.
https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/samples/msal-angular-v2-samples/angular10-sample-app/src/app/app.component.ts

Not exactly the equivalent, but it seems that I can use InteractionStatus.

==EDIT==
There is a detailed documentation on that page. Damn, I just had to read a whole document instead of jsut skimming the upgrade guide.
https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-angular/docs/initialization.md#subscribe-to-events

Here is the code from the link.

import { EventMessage, EventType } from '@azure/msal-browser';
import { filter } from 'rxjs/operators';

this.msalBroadcastService.msalSubject$
    .pipe(
        filter((msg: EventMessage) => msg.eventType === EventType.LOGIN_SUCCESS)
    )
    .subscribe((result) => {
        // do something here
    });

Also there is an upgrade guide now.
