You can use observable.pipe(take(1)).subscribe to limit the observable to get only one value and stop listening for more.

let firstName: string; 

        this.insureFirstName
            .pipe(take(1))  //this will limit the observable to only one value
            .subscribe((firstName: string) => {
                this.firstName = firstName; asssgning value 
            });
        console.log(this.firstName); //accessing the value
