How to create a notification system about the downtime

I want to create a notification system and send it to all clients regarding the downtime of the server whenever we try up upgrade the server or update the codebase. Any pointers on how to achieve this? During this downtime, clients will not be able to connect to the server as it would be offline. I am aware that the heroic team cannot support self-hosted server-related queries, anyone else who handled this in your game?

Hello @Sathyaraj, you can use notifications to let the clients know of the downtime head-of-time.
