Real-Time Internet Connection Status Check and Notification

[miladsoft]

We need to implement a feature in our Blazor application to check the user's internet connection status in real-time. Specifically, we want to display a message to the user whenever they lose their internet connection and hide the message when they regain connectivity.

how would this work? a timer or when they try to connect to a relay or indexer?
Is it not already the case if internet is lost it will throw and they will see some error message?
