title: How to send push notification to 2 devices without creating topic or group using just the FCM tokens in Firebase?
body: <p>I just need to send push notifications to a handful of devices. I have their device tokens in an array. Do I need to create topics or groups for this?</p>
  
  <p>I can send push notifications individually using a for loop, but is there a better way to do this?</p>

  <p>has answers to use FCM Token  and groups, which I have clearly stated that is not my requirement. As far as 'registration_ids'  mentioned by other question is concerned its not mentioned anywhere in the official docs , if it is mentioned then please point it out as a valid answer. </p>
