Hello Ramadan,

I understand the challenge you are facing. Some of our clients working with Zendesk had the same question. In some cases, the notification app you are referring to "did the trick". But the use case was very specific: inform every agent currently working in Zendesk about something important. This way, they don't need to check other tools or business emails.

However, you say you need your agents to acknowledge those updates. This is not possible with the notification app as it is a one-way broadcast only. I'm not aware of any app in the marketplace that can do that. A custom app might help.

Then again, this whole use case sounds like something that is already solved outside of Zendesk with other communication tools like Slack or even basic business email:

Create a channel in Slack for updates only. Advise your agents to activate pop-up notifications. Then, whenever an update is shared via that channel, have your agents acknowledge the receipt by responding in that channel. This way, you have your acknowledgements plus the log of who did and did not see them.
You could potentially combine both: send out an important update via email or Slack. Then send out a notification via the app you mentioned whenever there is an update. Agents will then reply to the email to acknowledge or go to Slack, where the full update has been posted.

I hope that helps
