How to use angular async binding

Question

I want to do something like <span *ngIf="admins.includes(name) | async"> where admins is defined in the component class as admins:Observable<string[]> I know this does not work but is possible to achieve this in any way?

Thanks so much for help!

What is your actual goal? To imply show the span if name exists in the admin list - yeah? — Zze

Yes - that is correct. It admins was a simple list instead of observable I would do that <span *ngIf="admins.includes(name)> — Anand

The async pipe needs to be on the observable itself like below.

<span *ngIf="(admins | async)?.includes(name)">
