Is it possible to actively revoke already sent notifications from the server?

Non viene indicato alcun file sorgente o test. Inizia dall'API di notifica del server e dal comportamento di consegna, quindi determina se la revoca può coprire le notifiche già consegnate, i client offline e tutti i dispositivi sottoscritti. Il lavoro è completo quando esiste un limite di capacità documentato o un piano di implementazione.

Question

I need my server to be able to actively revoke already sent notifications from all clients. By revoke I mean that the already shown notification should be hidden automatically w/o any user interaction.

Is this possible?

I did not find any information on this in the docs, so I guess it is not possible but I wanted to be sure.

My use case

I have a personal reminder app to which multiple clients are subscribed to (e.g. desktop pc & mobile). When interacting with the notification on 1 client, it should be removed/revoked on all other clients. E.g. when clicking on the notification on a desktop pc, it should be automatically removed on my mobile and vice versa.

Also:

• The notifications shall be revokable from my server w/o any direct user interaction with any notification.
  E.g.: The notification has been sent to all clients. I don't click on any of the notifications but open the reminder directly within my web app -> All notifications shall be revoked.
• If a client is offline whilst the notification is being sent and the notification is revoked before it comes online, the notification shall never appear on the client.

Some more context:

ATM I'm using web push in combination with a PWA. This works technically and allowed me to implement all the features I need (revokability etc.). However, notifications on Android are very unreliable. Some appear an hour after they have been sent by the server, some don't ever appear at all. I'm therefore looking for alternative ways to notify my clients.
