As the time of writing this answer, In AngularFireObject you have to use either valueChanges() or snapshotChanges(). You can read the documentation here

Coming to your concern if you simply modify your code from

item$.pipe(take(1)).subscribe(item => {})

to

item$.valueChanges().pipe(take(1)).subscribe(item => {})

will solve your problem.
